Sonic Frontiers - Undefeatable | Reacting To Video Game Music! 

Kellin Quinn did all the vocals. Even the fry stuff. His vocal range is impressive. Also, people (including myself) commonly think that its a girl singing when Kellin does vocals and they don't know better, glad to see the tradition continued.

If you thought this was heavy, you're not ready for "Break Through It All"

Another episode of "SEGA didn't have to go that hard for a Sonic the Hedgehog game, but they did."

Tomoya Ohtani was super proud of putting an 8-string guitar on the soundtrack, which is weird considering Ohtani is the synth hiphop guy from SA2. He's an incredibly versatile composer. Boss themes and the main theme "I'm Here" are like this. (I love I'm Here btw)

I was telling my metalhead coworker about the music in this game and my lead in was basically "do you know what Sonic the Hedgehog and Sleeping With Sirens have in common?" And it blew his mind

Undefeatable has quickly become one of my favourite Sonic boss themes, Kellin Quinn killed it with his vocals on this track and the other Titan themes. With how hype Undefeatable is, you’d think it would be for a late game boss, but instead Tomoya Ohtani (the composer) decided to go hard on the first major boss instead.

Fun fact. The offical song on RU-vid has over 10 million views and also on Spotify.

Sonic’s always balanced being this very marketable mascot character, while also having this far “edgier” side to him, for lack of a better word. Games like Adventure 1/2, Black Knight, Unleashed- Tell stories with a lot of legitimate depth to them, and with games like these, Sonic’s grown this very stylish edge to him. It’s very shonen-y. Sega neglected that side of Sonic for a very long time, but Frontiers feels like it’s equal parts “a breath of fresh air” and “a return to form” for what the large majority of hardcore Sonic fans have grown to love the series for. The plot is somber, it deals with the concept of growth, mortality, and what it truly means to be remembered- and yet it’s been decades since these characters have even felt like themselves, and not just Mario-style mascots. It’s so refreshing, and the soundtrack is a reflection of this. The music goes all over the place, from these beautiful, somber, sweeping orchestral movements, to fast-paced, bombastic-yet-gritty 2010s style EDM, to the intense heavy metal of the boss/main themes, to even mournful piano ballads. Frontiers may not be perfect, but for all it does well it is an amazing game, and a stunning love-letter to the fans. I have never had as much faith in the series as I do now, and I can’t wait to see if you’ll do any more Frontiers’ reactions, as theres so much to enjoy within its OST.

I just like seeing people’s initial reactions to this song because it’s almost always “this is insane”

You know Sonic isn't messing around when this is the first boss theme. He's a man on a mission, and giganto was the perfect roadblock to display what his resolve looked like

The Titan bosses themes literally carried the whole ost album to top 10 US and worldwide Spotify ranking last year 😭

Sonic is such a joyous un-apologetic melting pot of genres. And like 99% of them are all amazing.

Undefeatable solidified in my mind that literally NO GENRE is off-limits when it comes to Sonic music. I look forward to the day they try some more obscure genres, like shoegaze or like math rock or something. Shit would be tight.

It's really just the Boss Fights that are like this. And this song just has one vocalist, which was indeed Kellin Quinn (A dude btw). There are two more songs that are in the backlog, that feature Kellin. The rest of the soundtrack goes for a different vibe. Also. Tomoya Ohtani (The Composer) said parts of Frontiers' Ost, use a 9-String guitar. Kinda have a feeling we know what parts now.

Believe it or not, it's not *completely* unprecedented for Sonic to have guest musicians like Kellin Quinn. Back in the day, Johnny Gioeli was a hard rock vocalist for Hardline and Axel Rudi Pell, and it shows when you hear his vocals in What I'm Made of, Live & Learn and Never Turn Back; and in Sonic & the Black Knight, Marty Friedman, the lead guitarist for Megadeth, and Emma Gelotte and Tinna Karlsdotter, the vocalists from All Ends, collabed with Gioeli on the final boss song With Me; they also got Jared Riddick from Bowling for Soup to do Endless Possibility, the theme for Sonic Unleashed. Also, they got Tyler Smyth from Danger Kids to work on tracks for 2 Sonic games before this, and he was an opener for Sleeping with Sirens iirc, as well as collabed with Quinn on Find Your Flame for this game.

the feeling of absolute SHOCK everyone had when they discovered this was the theme of the -first boss-, even as long time fans of the games, was amazing, it was like, a collective 'WHAT' because of how different it was from every other vocal track in a Sonic game to date, though we all agreed it was an incredible piece of music. My personal favourite is actually Break Through It All, but Undefeatable is a close second! Thank you for reacting to it, this was cool, you looked like you had a lot of fun with it! :)

Now imagine this playing as you're going up against 200 foot robot. He slammed you against a wall a few hours into the game, and you're right back in its face now. But now you hold all the power. And you're refusing to back down. Actual life-changing experience

Kellin Quinn is such an amazing vocalist. Glad you enjoyed Undefeatable, Jesse! Can’t wait to see Find your Flame….

The whole Sonic Frontiers soundtrack is actually very diversified :] The big metal themes are for Boss-fights only and they stand out a lot. But the game is actually filled with other genres like EDM (that is for the short "fast-paced" levels set in a digital dimension), and more orchestral music using a bunch of diverse instrument for the open-wold area! IMO the themes of the islands (open-zones) are really overlooked as a whole and people usually go for the big vocal themes and the EDM music. Hoping you will eventually make the other Boss-themes!

It's insane how much this song actually fits in game. Super sonic whaling on a giganto enemy with metal music

The Sonic Frontiers soundtrack is so incredibly diverse, there is so much too unpack! From the heart-pumping boss themes, to the melancholic island themes, to the more up-beat EDM-Style tracks of the cyberspace stages. I hope you react to more of this amazing soundtrack!

It's About Damn Time, "Breath Of The Sonic May Cry: Revengeance", had its daybew. Also without spoilers: Undefeatable: The best right off the bag. Break Through It All: The best after multiple listens. Find Your Flame: Metal Gear Rising: Revengeance successor.

It is a toss up for me Between Undefeatable and Break through it all. Both are so good. They also both go with literally anything

Up until this point, escape from the city was the 'The' Sonic song. And then came Undefeatable and finally it had some competition.

Happy to see you enjoyed it!! This track caught me super off-guard when I was playing the game for the first time, I was practically jumping from my seat while playing. 😂 I CANNOT wait for you to hear Breaking Through It All, it's my favorite boss track in the game. Undefeatable is fantastic and makes a great first impression, but Break Through It All was the kind of heavy stuff I didn't know I needed to hear from a Sonic game, and the DRUMS on that one oh man. I did submit some Cyberspace tracks as well, so I look forward to that too! As others have mentioned, this game has a very diverse soundtrack. It's kind of hard to submit the island exploration themes since they're all orchestrated with seven movements for each island, changing movements every time you collect a Chaos Emerald on that island. But still, the movement OSTs are great too. You transform into Super Sonic at the end of each island, and get a kickass boss fight spectacle with great music.

When I had first heard this I was like "What in the sleeping with sirens" because Kellins vocals are incredibly recognizable. It is cool they got him on board for the entire OST. It fits the game well.

Crazy thing: This is the first area's final/major boss. Crazier thing: The gameplay goes as hard as the music. Craziest thing: _ALL_ the major bosses are like this. xD Except the final-final one for some reason

This is THE Sonic Frontiers songs. Already as iconic as some of the Adventure theme songs and more, it sounds on the first boss battle which is a giant titan unlike anything seen outside of previous Sonic boss battles and it's even heavier than stuff like Metal Gear Rising. Long live Sonic

I’m genuinely dying laughing here. Add to that I actually am so happy that you enjoyed it so much. Like, HES A LITTLE BLUE HEDGEHOG WHO COLLECTS RINGS.

My jaw hit the *floor* when this music came on during my playthrough of this game. As soon as the fight was done, I was immediately hitting the internet to try and find the track. Sonic has had some intense music before- His World (Zebrahead version) and Infinite's theme, for example, are meant to hammer into you- but full on heavy metal like this was just such a jaw-dropper for me. I truly adore the boss music in this game, they just do not miss.

Sonic just has peak music.

So what this fight actually is: You fly through the sky in Super Form while beating the ever-loving crap out of a legit mountain-size boss in a Devil May Cry-esque combat system. Except you are free-flying. I shit you not. Sonic has ascended with this game. xD

All the boss titan themes are so good in this game. Break Through It All, Find Your Flame, and I’m Here are must listens for sure.

FINALLY! Jesse, this is Ashton, one of your requesters. For years, I’ve been watching your channel and I wanted to give something back to you for all you’ve given me. Undefeatable is easily one of my favorite Sonic songs and I haven’t even played the game yet, I just love its soundtrack that much. Its lyrics make it an amazing power-trip song. This request was my thanks to you for being such a great entertainer for all these years. Keep up the great work!

Sonic's musical coverage is always a piece of musical trends among teens of the respective times. Back during the old SEGA days, it was a very synth-heavy pop/funk mix, which fit the late 80's/early 90's perfectly. With the transition to 3D, Sonic was reframed into a rock direction, aligning with the rock and metal craze of the early 2000's that eventually culminated with a wave of emo rock and nu metal lasting to this day. But Sonic Frontiers followed the rise of metalcore and alternative metal that we're seeing right now. The songs are never trendsetters, but they're prime examples of great music with a strong sense of style and fun. And Frontiers went above and beyond once again in delivering a style of music you never would've associated with Sonic, but it just works amazingly well! I can honestly recommend the other vocal tracks, especially "Break Through it All"!

Great to see you listening to Frontier's music! Frontiers, despite being relatively new, has already left a big impact. Sonic Team considers it the start of the "third generation" of Sonic games. It's broadly considered to the best game the series has had in a while and the soundtrack in particular has been widely praised even by Sonic standards. As others have mentioned, the ost for this game is very diverse with the metal tracks being specifically made for the bosses. Since Super Sonic hasn't been very prevalent in recent games, Ohtani wanted the boss tracks to be "powerful" and "iconic". Which, considering the game's ost titled "Stillness & Motion" hit #1 on Spotify in the US and #6 globally, is a goal I think he successfully attained.

I love when jesse goes into a sonic song he never knows what he is going to get. Could be butt rock or a poppy upbeat number

Not sure if I anyone else mentioned this but Sonic Frontiers' soundtrack was number 6 on Spotify when it came out not sure where it is now.

So happy you reacted to this! Sonic Frontiers is my favorite Sonic soundtrack, and is actually my favorite Sonic game currently. Stand out tracks are all the boss and mini boss tracks (especially Ghost), and the second movement of Ares Island.

personally, I think the best way to experience the boss themes is hearing them for the first time in-game. shortly before this, you would've only heard some somber overworld music and a few Cyberspace tracks that make your head bop, but then you get to the first boss and BOOM you're hit with THIS, and it rattles your brain a bit cause it came out of nowhere. I honestly love that it's really leaning toward that shock factor that immediately pumps you up and ready to throw hands (Sonic punches and kicks as his basic combo in this game). The boss themes are truly amazing and out of this world.

at last, finally someone put this man onto sonic frontiers jams. Now we just need to get him to rock with the other songs and experience what he been missing

Oh HELL yeah. I'm so glad you're doing these. I hope someone requested Break Through It All because that's my favorite of these boss themes.

All boss themes in Sonic Frontiers are amazing.. It really brings me back the older 3D Sonic games from the 2000s with this kind of vibe. 😇

Whenever Sonic games need music, they rub the lamp and the genie grants them a wish to make bamgers

"Ha ha ha ha... *SONIC* ?" It's so cute 😂

I've learned how to scream because of this sound track. My voice hasn't been the same since. Love this track and the others they're just so tasty!!!

Frontiers has such a nice soundtrack, from the chill/erie open-zone ones to the metal scream-o esque boss themes, down to the drum and bass cyber space stages, hope you get to react to more of it!

Been waiting a while for this one. It's the top track from your list (thats not one of mine) that I wanted you to react to. Didn't disappoint!

Oooooh this is gonna be GOOOD to see you do Sonic Frontier stuff! Can't WAIT till he gets to "Find your Flame."

Finally! Been waiting to see you experience this, now onto the other, more intense boss tracks!

I hope one day you will react to Sonic Unleashed's egg dragon theme, it is one of my favorite themes and one of the best boss themes that Sonic has

I absolutely LOVE that concerned "Sonic?" At the start, I had the exact same reaction 😂 the cheery/rock tunes go to metal sounding tracks and its awesome

Has nobody got him to listen to 'Infinite' from Sonic Forces?

My favorite line in this song is "You think I'm on 11, but I'm on a 9. Guess you don't really know me." It's like you can hear Sonic saying, "Oh, you thought THAT was fast? Wait 'til I start actually trying." And then just kicks on Super Sonic and takes off. SO sick.

This soundtrack hit the top 10 on spotify and I assume now you know why.

The first time I heard this, it blew me away! It's so high octane and just gets you hyped up. I also didn't know Kellin Quinn's voice was that high-pitched.

this one was a long time coming, but your reaction is so great jessie :) i remember hearing this song in the game and being excited to hear your reaction lol

GREAT reaction dude. The Frontiers soundtrack is great and all of the boss themes are amazing, and when it comes to the levels, level 1-2 is a banger as well. Also love your use of the Battle Hub theme from Street Fighter 6 for the background music. It's so chill.

it is well worth noting that the lyrics of this song are from the perspective of Sonic. you can see his cocky attitude from lyrics like "think I'm on 11 but I'm on a 9", and "I'm what you get when the stars collide". You feel his undying will from the lyrics "I'm hanging on to the other side, I won't give up 'till the end of me". This song is not something you would expect from a Sonic game (neither are the other boss themes for that matter), but this song is nonetheless pure Sonic

Kellin Quinn is one of my favorite vocalist. Always loved him in his band Sleeping With Sirens. When i heard this song for the first time last fall, i couldn't believe he did the Sonic Frontiers vocal tracks. Huge Sonic music fan, so it was like two of my favorite worlds colliding!

Hell yeah, this is what we were all waiting for 🔥🔥🔥

I've been waiting for this reaction and finally it's here! Thank You for your reaction

Now to wait for Break through it All and Find your Flame, tracks that belongs to the other 2 major bosses and maybe I'm Here as well! I always enjoy your music reactions as well as the thoughts after it

I love Sleeping with Sirens Kellin Quinn has such an amazing voice I was so excited when I heard he was working on this game and all the boss music is fantastic!

The second "Break Through It All" and third "Find Your Flame" boss fight OST's will blow your mind even higher, bro! But whenever you're ready. Then again... I don't even have to see you react to it. You just need to hear it!

One of my favorite things about this song and by extension the other songs is how easy it is to understand the lyrics. It's rare for a song of this nature to have actual lyrics you can comprehend.

oh and of course great reaction1 it was fun to see you have so much fun with it!

IVE WAITED SO LONG FOR HIS REACTIONS TO THESE SONGS!! I REALLY HOPE HE REACTS TO THE OTHERS

Awesome to see you finally reacted to this song Jesse and glad you enjoyed it. Now, it'll be interesting to see you react to Find Your Flame, which does have dual vocals in it. I could be wrong, but from my understanding or at least from the bits I've read and seen online. Tomoya Ohtani, who's one of the main Sonic music conposers and who composed this game. He writes and does all the music (not sure if he has other artists' come in and help with song writing or not as I could never find that imfo). On more then one occasion though he will typically bring in guest vocals to sing, I'm also not sure if it's a case that he sends them the track and has them write lyrics that they feel can go with the song or if he already has lyrics written.

I've been waiting for this for so long

Omg we're finally here this is not a drill!! Thanks Justin and thanks for choosing this. I was SHOOK 😂

I jumped with joy at seeing the notification ! What a fantastic thing to wake up to !! Welcome to Sonic Frontiers, we have : djent/heavy metal, beautiful ambient orchestral, not-so-ambient orchestral and SO MANY different kinds of EDM, including freaking lo-fi of all things, and other hodgepodges of beautiful sounds with driving techno elements ! Hi ! Real quick word of advice : there's official SEGA uploads of the whole Frontiers OST on youtube, you should go with those ! There are some fan recordings that have some splicing errors, because all the boss tracks do phase transitions. If, or when, you do the other Frontiers boss themes, please try to go in order ! The order is Undefeatable ( you are here ), then Break Through It All, then Find Your Flame, then I'm Here ( which is also the main theme of the game ). There is a final final boss track, but while it's imo a fantastic track, it's not a lyrical song, and definitely not in the same style as the others, so people generally don't recommend it for reactions. It's called I'm With You, if you're ever interested in checking it out. You may also get requested to listen to One Way Dream, which is the true ending theme, and Vandalize by ONE OK ROCK, which is the normal ending theme and a licensed song, so not made directly for this game. Have a nice day Jesse ! Thanks for the treat !

The contrast between this and not only past Sonic themes but also the much calmer area themes you hear for most of the game definitely give the boss tracks in Sonic Frontiers that "whoa" feeling

This was awesome. First time hearing this as well.

It took me a while to realize the vocals were done by only ONE PERSON. Quinn has INSANE range

Please tell me Break Through It All is following soon, this OST is incredible

I've been waiting for this!

Oh man i really hope you do break through it all while you’re at it

I've been waiting for this

Aayy! Was was hoping you'd pick this one up!

Yessirrrrrrr 🤙 I was wondering if this song was gonna make it to the channel

Sonic Frontiers goes HARD. Glad you enjoyed this. Gonna HEAVILY suggest Break Through It All and Find Your Flame, the other two main boss themes. I'd also suggest the Yesman10 music videos, since you can catch glimpses of the boss fight it plays over.

Sonic frontiers has a phenomenal soundtrack from rock to dubstep to orchestrated over world themes it is amazing I was looking forward to this reaction and I love it👍🏿

I've waited like a year for this, looking forward for the rest.

I was wating so long for this one. FINALLY

I was wondering when you'd react to this one haha, guess that request list really is packed huh? Seriously though, if you can, react to the other boss themes as well, they're all on the same level of insane quality, it's criminal that this game never got any awards for its music.

As far as i know this was one of the first times metal has found its way properly into a vocal theme for the sonic series and they nailed in immediately

//Ive been waiting for this LETS GOOOOOOOOOO

Alternative title: "That Music When You Axe-Kick A Skycraper-Sized Boss Into The Earth's Crust (And It's Not Just A Cutscene)"

Ah ! I knew it wasn't going to be long before this one Cannot wait for *Break through it all* now

Another song in this game is Break Through It All and it's probably the song that goes the hardest imo, good stuff.

Break through it all is next BABYYYYYYYY

This has bin my favourite song for a while now but I still can't believe it's sonic

I haven't clicked a Jesse reaction this fast in a while.

Couldn’t get here fast enough for this one

We will be waiting for the break through it all reaction

All the boss themes are basically like that whenever you get the chance I'd give a listen

Tomoya Ohtani composed this song, as well as many of the stage themes! =) Oh, that upload certainly has some compression. Frontiers' OST is uploaded on RU-vid officially, so in case there's more Frontiers songs you'll react to, use those for the best audio quality! =D

Literally every boss theme (and then some) in this game is a BANGER😎👍🏻
