I think it's also an age thing. As teenagers, we are trying to define ourselves. At that age music plays a big part of our lives because it's a trying time and music really hits how we are feeling then. Same way is fashion. I mean going through late grade school and high school I had plenty of looks. I had the long skater cut colored Manic Panic white (man did that go well when I got back to Catholic high school

), then had a more of a preppy look, and then the rap side.
Now I have a more ecclectic music taste and I have my own style.
Point is that music can't always define your style if you listen to a lot of genres. And added on that I re-iterate the age thing. I'm not saying that teenagers are fickle and change styles all the time to fit in. Don't get me wrong. I just think that teen-agers are more enthusiastic about music and are more excited to throw themselves into something they like, music, style, fashion, politics even sometimes...
Am I still making sense? I should stop drinking and posting...
