I like the way you have tuned it, but I really wish you didn't add that much unnecessary SFX. For example at 2:27, it only caused some abrupt pain to my ears and it did not match with the song at all. I guess some minor SFX are fine, such as some subtle gun shots or glass breaking, but it's better if you just left it as it is. Other than that, thank you for you efforts to make the original song into a wonderful nightcore.
+Sirender Hi ^-^ Yes, I know some sounds are really annoying. This at 2:27 is so terrible. I know :D I once heard it before I fell asleep. You can't imagine how scared I was when I suddenly heard this noise. BUT I didn't even changed anything and I didn't add anything. The SFX were there before I make this nightcore version of this song. It's because it's the audio of the original video. And in this video there are all this more or less annoying SFX. SORRY ABOUT THAT! It's almost two years ago I made this and I think I really was a beginner in terms of making these types of videos. So please don't kill me T____T ....Okay joke's over. I totally agree with you, but I hope you like it ... maybe ... somehow ^^'
***** It's not your fault at all actually, I just realized that you originally got it from the official video of this song itself instead of the lyric one. Sorry about thinking you have done that. But as I subtly stated before, I still like it despite of the displeasing rackets. Maybe it would have been better if you use the lyric video and not the actually music video -- they sometimes digress from the actual song. Though I am aware that this suggestion is very late, lol.
