I think that the media helps to shape our individual and group identities. Certain groups have music that helps them create their traditions. Personal music tastes help to describe what the individual is like. I think that the music we listen to shapes who we are, but we also are not passive beings, left to be shaped by our surroundings. We actively decide what music we listen to, and thusly like. I don't know that the individual groups that I like to listen to sets me into any particular category, though I do know that some music that I dislike eliminates me from certain categories.
What do your musical tastes say about you?
