Yeah, absolutely, I think it's mostly an age thing.
I believe that things like music, books, and films have the biggest impact when you're in your teens/early 20s. You can still like loads of new stuff as you get older, but I don't think you ever "connect" with it in quite the same way. I still like the bands I was into at your age, maybe you'll find the same when you're my age! :P
Then again, I find, now, that I also like bands from the same period - '70s/early '80s - even if I didn't listen to them at the time. So maybe it's just that the music from "your own era" somehow reflects the "spirit" of the time it was recorded, and that's what you connect with.
Ah, I don't know. :?
