'원 (Time After Time)' Recording Behind the Scenes 

I can now understand why NINGNING got accused of lip syncing because her real voice exactly sounds like the studio version.

BoA's husky voice, Wendy's soulful voice, and Ningning's crystal clear voice makes this song very powerfulllll

BoA and Wendy are already known for their superior vocals but with this song, Ningning really proved herself as one of the best KPOP main vocalist ever. I'm so proud of her. She did not lose at all compared to her seniors. All three of them are a marvelous singers.

Look how ningning effortlessly hit every notes with ease and just playing up in the recording while EATING UP,yup that's our one and only NINGNING

You know the song is successful when we get recording behind of it. Will never get tired listening to BoA, Wendy and Ningning's voice

Wendy's vocals are no joke. Her vocals are outta this world!

Wendy said "no cameras I'm here to sing." and then gives a master class in nuance. Ningning's whistle notes, clutching her hoodie to avoid the camera.

How tf ningning make it so effortless 😭 her mixed register is so healthy and resonance

Ningning's vocals is so powerful and she looks so effortless singing those notes like?!!

Ningning doesn't need any autotune her voice is so clear

NINGNING IM SPEECHLESS! SM GIVE MORE HITS TÔ NINGNING!!!! SHE IS THE BEST VOCAL OF 4th !!!!!

SM = house of vocals BoA = Seasoned Veteran NingNing = Rising Star Wendy = Eternal Legend

WENDY JUST STEPPING INTO THE RECORDING ROOM READY TO BELT LIKE IT’S NOTHING 😭😭 HER TALENT

Ningning can hit both high notes and low notes..and singing along with her seniors.. plus the way she can layer her voice in different variations.. that speaks so much about her talent, she's the youngest among them too.. Love this collab so much

I’m actually so impressed how much depth NingNing’s voice is at such a young age. I hope she gets more of a chance to show this in Aespa!!!!

Wendy's throat must be coated with diamonds. She has to have one of the most beautiful voices I've heard in my 5 decades on Earth.

NINGNING is such a baby in that hoodie SO CUTEEE!!! Her vocals are always effortlessly on point! SM family's maknae y'all! 💯

Gosh! Wendy's vocal are insane. She recorded it over and over but still, her voice did not crack or lost her voice or anything wrong happened. She still continues with her great voice. Just wow 😮

I need a GOT unit with BoA, Wendy & Ningning. They compliment each other so damn well. I NEED IT like I need air 😭

NingNing's vocals are no joke. Super perfect! Our main vocal NingNing!

NINGNING JUST PROVED WHY SHE’S AESPA’S MAIN VOCALIST. SHE KEPT UP WITH THESE LEGENDS. DAMN.

and to think ningning is only going to improve even more in the future when she's already this amazing 😭😭

we know that boa and wendy is top tier singer but lets talk about ningning vocal, she is so talented😭😭

Gosh Ningning’s lower register always take my breath away, this talented young woman is the backbone of Aespa’s vocal.

Wendy never fails to amaze with her goldy vocals... THE main vocal indeed phew

No one can touch the vocal of an SM idol. Indeed, SM water is something else lol. And Wendy’s vocal??? Damn no wordsss

Ningning's voice is really strong and amazing

ningning vocal is no joke. how can she hit the highnotes so easily ㅠㅠ

Wow Wendy sounds exactly like the final version she has such an amazing grasp of her voice

ningning really is the best main vocalist in this 4th gen. i mean HER VOCAL IS SO OUTSTANDING!! she also produce and make her own song even dance like a main dancer omg shes really the IT GIRL😮‍💨😮‍💨💥💥

Wendy's vibratto is flawless and crystal clear omg

I'm obsessed with NingNing being an actual human burrito while singing flawlessly. She's the definition of Next Level.

wendy's got such great control over her voice WOW like the producer gives her instructions to make it "soulful" place vibrato in a syllable and SHE ABSOLUTELY NAILS IT

WOWWWW NINGNING!!!

닝닝은 진짜 제일 억까가 많이 붙은듯.. 이렇게 잘부르는데 진짜 ㅠㅠ 너무좋다.. 웬디는 이 셋중에서 제일 비음없이 시원시원하게 올리는 스타일이라 귀가 뚫리는 느낌이고 보아는 진짜 노장은 죽지않는다는 느낌.. 왜 보아가 아직까지 현역인지 알수있음.

Ningning's layeringggggg. And her high adlibsss. Her vocals are NO JOKE.

Wendy vocals omgg 😲 😱 😍 💓 💖 😭 😲 ❤️ 💙 💜 💖 💗 💘 ❤️ 💙

I’m a reveluv and wendy still shooks me till this day. She’s just amazing.

닝닝 목소리 너무 예쁘다.. 특히 저음이 좋음. 보아 웬디는 말할 것도 없이 좋다 ㅜㅜ

Ning Ning surprised me. Her vocal skills are very mature and healthy. All the high notes are easy to sing. I look forward to her growth in the future.

Wendy can sit in the TOP 10 BEST VOCALIST IN KPOP

Ningning voice's really suit with this song. Her low and high note was so perfect. Her breath control make her voice hear so soft and clear

Ningning's vocals never let me down, her voice is very very very very beautiful ❤️❤️❤️

Ningning's well-projected lower register, precise vocal agility, and soulful vocal dynamics/volume control saved her overall vocal technique and ability which made her earn as one of the best female "kpop" vocalists in the 4th generation... If she further develops her mix in the upper-belting range and make it more balanced (optimal chest and head coordination in her mix) as well as improving the consistency in her upper-register, she will eventually snatch the title as the best female main vocalist of the 4th generation (considering those above her regressed vocally or remained the same vocally) Note: a heady mix is far from being unhealthy (as heady mix/belt prevents/reduces vocal fatigue and stress since a chestier mix tends to be more powerful yet more stressful), it's just that it's not the most optimal way to mix.

Wendy’s voice is just world class. Damn! 7 years since I’ve been her fan but I still cant grasp how wide her range is, how many voices she can produce depending on the song. Please sing for a long time Wendy 💙🫶🏼

Ningning's vocal gymnastics is so satisfying to watch. Can you believe this is from a 20-year-old young singer? Those rich low notes, bright and powerful high notes, and effortless changes between chest voice and mix/head voice. Also her whistle notes at the end. Mariah Ning2 Carey is just **chef's kiss**

They better give Ningning more chance to show her vocal ability like it is such a waste gatekeeping such Gem

ningning's voice is so soulful and attractive, especially when she sings in her lower register 😩❤ also the nose scrunches she does lol i love her smmm

BOA and WENDY being so *SUPPORTIVE* to NING,it's warm/wholesome and what I like about *SM Family* most. *Every SM seniors help there juniors to shine* ! 💞🦋💯

Wendy is outstanding👏 This is the best song in the album for me❤

THE WAY NING NING'S SMILING WITH THAT FREAKING HIGH NOTE??? YOU REALLY KEEP ADMIRING ME EVEN MORE GURL!!!!!

NingNing looks so relaxing and having fun while singing those notes, from low to high. Powerful main vocal indeed.

Ningning, Wendy and BoA's voices are a perfect mix. I'm really impressed with Ningning's voice, how she sings different notes and forms harmonies, she's really really perfect to sing the song. Even When she could sing lowly, she was destined to become an idol with a amazing voice. 8:11 8:15-8:30 8:49-8:56 9:22-9:43 9:46-10:02 10:07 , 10:13 , 10:17 , 10:20 , 10:23 10:30-10:52 layer 1 10:54-11:00 layer 2 11:01-11:22 layer 3 12:19-12:24 Look at this! 12:35-12:43 12:54 13:05 There isn't even a difference between the studio sound and the original sound, so amazed.

ningning is freaking amazing, her voice makes me goosebumps

wendy is crazy. she sings with such perfect technique

If you been red velvet fans since beginning, you just know when Wendy hit the note "shine on me" this girl gonna be one of the top vocalist in kpop legendary

Wendy's vocal is soo perfect, how can someone makes me fall in love even harder like Wendy did to me 💙💙

Wendy's vocal is on another level. She is so freaking talented!

Ningning‘s voice is TREASURE. I can‘t find words to describe how perfect it is.🥲

닝닝 괜히 메인보컬이 아니네 음역대 엄청 높다ㄷㄷ 가성 쫙트인거봐

I still remember when wendy told us, she did recording after her schedule (youngstreet) even she did it on christmas eve, not only recording but also practicing whenever she had time.. hardworking wannie

When it comes to Wendy, there is no difference with the sound of her vocal in live and recording, she’s just so perfect!

This song is as beautiful as BOA, Wendy and Ningning's vocals. Powerful vocals and great harmony. A great job!

닝이 한국어 연습 진짜 열심히 하나봐 ㅜㅜ 발음이 어쩜 이렇게 정확하지😭😭🦋

Wendy nailed it!!!!! 🔥

Time After Time : 1. Wendy's beautiful voice 2. BoA's unique tone 3. Addicted adlib from Ningning

ninging did high notes like it was nothing for her while my soul would never in that level😭😭

Wendy is Queen of Technique. The way she can adjust almost immediately after one correction

ningning has the most precious vocals 🔥

NINGNING talent is out of this world just wow 🔥

This here is just more evidence on why Ningning keeps on drawing comparisons to Bada herself. Ningning’s vocals are just out of this world. Wendy well what can u say about wendy that hasn’t already been said. She is just amazing and a gem

I'm absolutely obsessed with Wendy and Ningning's voices. They're ethereally beautiful. Also Ningning recording in a hoodie is such a mood.

NingNing's vocal range from low note to hight note. So proud of aespa's maknae.

NINGING PROVING ONCE AGAIN SHES THE BEST 4TH GEN VOCALIST !!!

WENDY ALWAYS SHOWING WHY SHE IS AND WILL ALWAYS BE ONE OF THE BEST VOCALISTS IN KPOP!!!!!! HER VOCALS ALWAYS LEAVE ME IN AWE!!! SHE IS SO BRILLIANT!!!!!!!!!!!!!💙🔥

Wendy's raw vocal is the most beautiful vocal i ever heard

BoA's huskiness, Wendy's powerful voice and Ningning's clear voice is heaven❤️❤️

here for our maknae, our pride Ningningie 🦋

I've been stanning SM artists for almost 15years now so I already know how powerful their vocalists. For this video i want to compliment my youngest daughter Ningning, she show us why she is the Main Vocalist of AESPA. Thank you for your beautiful voice, our little BADA. 💕💕

That effortless high note from Ningning! ❤ One of my fave song from the album! ❤

Ningning vocal range is just mind-blowing but her low notes and singing style really suits blues. I hope she sang some solo songs I'm rooting for her

wendy’s part especially ‘you make me smile’ makes me cry idk why but she s make it so much soulful 😭😭

The way ningning is just smiling and having fun, while belting a bunch of G5 high notes. This is clearly not the highest she could reach.

Wendy's spectacular AS ALWAYS. She truly is such a gem like mygod how can such a person be THIS talented? SM truly lucked out with signing her under their label. That being said, WE NEED SSW2 WITH BETTER PROMOTIONS this time. 🔥

Wendy's voice is just insane, how she makes it easy to sing in different styles and notes, she really has this great control over her voice, plus it's power and soul, wow just wow! 💙

Ningning's voice mesmerized me 😻 she is definitely main vocal 👑🔥💖

ningning vocals are on point ! she nailed the song

Ningning will always be queen vocalist!!

I love NingNing's voice. She deserves all the praise and appreciations.

Ningning OMG how can u sing like that??? My troat hurts just hearing it hahaha amazing singer 💗💗💗💗

DAMN WENDY!!! truly the best vocalist of 3rd gen

*NINGIE'S VOCAL IN "TIME AFTER TIME" PROVED ONCE AGAIN WHY SHE IS 4TH GEN'S BEST VOCALIST* !!! 8:08 SHE OWNED IT... 🎶🎵🦋💯🔥

Wendy's vocal slayage is just ✨

닝닝 이렇게 잘하는데 라이브 더 많이 들려줘!!

Wendy’s vocal never disappoints us

Ningning really prove that she is the best 4th gen vocalist. Having the best low register and became the idol in 4th gen who hit the highest high notes in “Beautiful Christmas” by RV and Aespa collab. She really can sing every song that they give her, she have really flexible voice

닝아.. 어쩜 이리 잘할 수 있니.. 막막막ㄱㄲ... 몸에 전율이 솟아오른다. 가슴이 웅장해져.. ❤

I think Wendy have been underrated for a title unique voice, cause i know when people think about unique voice they always say from the other grup vocalist, but i think Wendy voice is unique too, she got so much a different tone voices, she can do a deep voice, soft voice and then just go for the high note in the same song, everytime she sing her line in english (example: byebye) but you can clearly hear her voice sounds so different in the same song, because i never heard the other grup vocalist do the thing like how Wendy did

Wendy’s vibrato though 🫂 i really love it

Falling in love with wendy again and again and again and again and again..
