Years ago, a research in Holland found that teenagers who listened to "all kinds of music" are the ones with the most problems. It must be because they can swing between many different moods. Not sure if that's type-related.
I think I use music to 'suck in' all of its emotional content and get familiar with its moods; I can listen to a certain album many times over a few weeks, subconsciously examining my emotional response to it, and once I understand it, I start listening to something else. I listen mostly to classical music because I find it 'richer', more layered, more varied.. If I didn't like classical music I would've probably tried to listen to as much different styles as possible.
Sometimes I wonder if the music I expose my brain too actually changes things; if I would've become a different person if I hadn't spent so much time in private, trying to feel things that I would've never experienced otherwise, and that most people of my age are completely unfamiliar with. I also wonder if I can become more normal by listening to popular radio stations.
I listen to a little of everything really- except for Garth Brooks and Celine Dion
I generally like things that are great for listening to while driving or doing something though... whether it's way over the top classical music (I like opera! ), Punk Covers of classic rock and country songs, ok... almost all punk that's not modern pop punk shit... dwight yoakam, I do like bluegrass and Hank Williams Sr as well, reflecting where I'm from I guess And don't most people like classic rock and 80s music?
In high school I listened to Red Hot Chili Peppers and Rage Against The Machine, since the adults did not approve
