Hi, I was never really into Thouhou, but Bad Apple and others were so much bangers and i’ve listened to them for year.
I remembered the OG Bad Apple video on Youtube so many years ago to be something like 3 and a half minutes, maybe 3:45 or something. But after I went back to listening a couple of years ago, the song is longer than 4 minutes, and so is the animated video, with a longer instrumental, a longer bridge, and a repeated verse.
The video I watched was the same, uploaded previous to 2010.
This is some form of Mandela Effect that I experienced and I wondered if someone got the same with this same song.
Actually going to answer your question here instead if bickering about terminology. Maybe the original song was shorter, and it was extended to match the video and include all the characters? Maybe someone uploaded a “nightcore version” and that’s what you remember?
