Oh, wow, that is really elaborate! It's awesome to know that you're in the same fandom as people this die-hard.
For some reason I haven't really seen that much Bad Apple. Maybe because it's so popular outside of Touhou lol.
As for Touhou music, I mostly like stuff from ShibayanRecords and EastNewSound. Recently I've also been really getting into Jerico's Law. He's really putting out some nice DnB.
Ah, speaking of Touhou... I have little familiarity with the franchise but this cover of Bad Apple is my favorite. I love instrumental covers of songs, be they orchestral or with region-specific traditional instruments.
I wonder what the music I listen to would be classified as? It's all based off of video game (Touhou, Kancolle) music, but none of it ever actually appears in the games. They're basically fan remasters, but much more professional and widespread.
I listen to mostly video game music nowadays. I can't say I listen to a lot of more contemporary anime music, as I haven't really been watching anything current. I post more on the video game music thread than the anime one.
