Oh I listen to my vinyl all the time. That's different than cassettes, though, and vinyl sounds better with age than cassettes do (when properly cared for). I've got some great classic rock and big band on vinyl. It's tough to find good stuff in the wild, but sometimes it can be worth it - like when I got the Blue Jays album (John Lodge & Justin Hayward) for $1.00. That's a little-known gem.
