I don't listen to any Black Sabbath, Led Zeppelin, Judas Priest or Iron Maiden, but not because I hate them. Its just not my thing. I don't want to listen to them just because everyone likes them. They are the music that inspired the bands I like and now I want to be inspired by the Opeths and such. But again, nothing wrong with any of those bands. They've done great things but I'd rather listen to Opeth, Nightwish, CoB, CoF, Dimmu Borgir, Theatres Des Vampires, The Haunted, Mortiis and stuff. Those are the bands I'll be telling my grandkids to listen to just as my elders like forcing the older bands on me.
