I dont listen to most Classic Rock, however there are certain types I do enjoy. Mainly I listen to Metal and Country (I know very odd combo). However I'll listen to generally every genre of music out there sans-reggae.
I've said it before and I'll say it again.... I hate reggae, Bob Marley makes me want to punch babies.
I listen to rock, alternative, metal, religious metal, some techno but only when a friend's listening to it. This isn't all of it, but yeah, I like variety. But there's certaine genres I wouldn't want to touch. Blue grass is one example.
