whoa this idea is cool! I don't know much about 8tracks but I have listened to some mixes and stuff (I'm more a Youtube person and literally all I listen to is Touhou sooo) but I just wanna say this is really awesome haha
Oh! Maybe you could do one for Medicine though?
For that matter, if anyone is into compilations of Touhou arranges/vocals I'm the person to go to for (non-popular/obscure) Touhou music I have like 700
