I like listening to music, and I like creating it, but I'm better at listening. I sometimes watch my music while listening to it. It's great fun. I also like to work on software that does various kinds of automatic music analysis so that my computer can help me organize my music and play the right stuff at the right time.
Mostly I listen to a cappella, techno (trance, house), Latin, and alternapop. My only not-just-listening music activity these days is RARB, which is mostly an exercise in web site development for me.
