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.
The human brain is a fickle thing. Most people experience optical illusions in the same way as each other. There's just certain patterns that tend to trick our brains. The same problems occur with memories. Certain patterns of memories are misremembered in similar ways between different people. Nothing as mysterious as some people think.
