I know a lot of people whose taste in music has remained what they listened to in high school . Most likely this is because of the fuzzy memories one associates with the oldies. There is nothing wrong with that. The danger lurks when one is still trying to be a hipster for the third decade. It just ain't going to be. This too is just fine. My philosophy is to like whatever music you like and that's cool. Music is only fun to listen to if you like it. If you don't like it why are you listening to it? Being one's own person and not just in line with the latest trends is coolest of all. What do all the trend setter's know anyway ?Good PR? I say like what you like and listen to what you like .
