I still enjoy the Beatles and Led Zeppelin and many of the classic rock songs I listened to when I was a teen, which dominated my musical landscape. I certainly would find some of them boring and overplayed, but the bands that I loved then I still love or really enjoy today. The bands I only kind of liked then are pretty much non-existent to me now. It's a weird dynamic since a good portion of my friends got into current music when they were in their teens and are now going back to find new music to them. I'm the opposite. They loved bands like the White Stripes, Black Keys, Franz Ferdinand and Gorillaz back in the early/mid 2000's and those are the bands I got into 2-3 years ago. Now they tell me how they really like Pink Floyd, Led Zeppelin or Black Sabbath. It's a weird dynamic and I'm simplifying their music taste and my own, but it goes to show that our musical taste certainly goes through some kind of evolution.
I typed all this down when I read the thread title and thought it was asking the question the other way. Moral of the story: slow down and read the damn thread title, ET!
