I try to listen to all kinds of music, man. I have found soo many times that I dislike music when I first hear it because I don't understand it, and then listening to it for a long time I start to get it and I love it. When I don't like new music, at first I blame myself for not liking it, then I blame my preferences after a while. New music meaning things I haven't heard before in music (not like new artists or songs, just new shit IN the music) .
I got into jazz 3 or 4 years ago, and I love a lot of the music in that category. I listened to rock from the time I was born. I got into blues and jam bands. I listen to some hip hop. I got into dubstep in 9th or 10th grade (4-5 years ago now?) cuz my friends were into it. It's gotten way boring since then. The shows are nice, but it's not shit to listen to just for listening.
Usually when I get together with friends we just show each other music and shit.
