Letting music be some kind of badge that defines us is strictly a teenage thing. We grow out of that as we mature (or at least most of us do!)
If I like something, I listen to it. I couldn't care less what it "says" about me.
In my high school, there were the Zeppelin people, the Floyd people, the country people, the punk people, the pop people, etc. I thought it was really stupid even then, and always ignored to follow my own tastes!
(The most ignorant people of all are the ones who think they are some sort of bad@$$es because they listen to death metal or gangsta' rap or some such thing.)
