I have tons of oldies, starting with Berry and Haley and the Comets (actually probably have a few older ones too) all the way up until they stop being "oldies" and become "classic rock".
When I was in HS, I didn't listen to "contemporary" (late 80s) music much at all, I listened to few things done after 1975. It wasn't until college when I got into alternative music and also listened to some late 70s stuff like Floyd and Zeppelin.
Anyway, I regularly talk to people who grew up listening to that music who don't know as much about it as I do!
