Oh that counts for me too, in fact I've downloaded almost all the music I have or bought it in mainstream cd shops. But then again, since commercialism and things like that didn't play any role in classical music, the reason that pieces became mainstream was probably because they are so beautiful

(in the ear of the beholder)
I have Chopin's first piano concert on CD played by Ida Czernecka, and love (t)his version ten times more than any video I can find on Youtube..unfortunately
