I love experimental rock (Mogwai, Sigur Ros, Earth), your face, not catching on fire, doom metal, underground and old school hip hop. Post rock and post metal anything.
I was a band dork, so you'll see a little classical pieces on here once in a while. My favorite band is Isis and all their branch offs (Old Man Gloom, Neurosis, Red Sparrows). I'll listen to Spanish stuff (I'm a beaner, I can't escape that). I like Japanese rock (Boris). Math rock is sweet (Japanther). Sometimes, when the weather is right, I'll listen to Sarah Vaughn. Justin Beiber nor his minions live here.
Sadly, I don't hang out with people who share my taste in music, but I'll throw in Dr. Dre before "shocking" them with the rest of my playlist.
I don't listen to whiny rock music (aka what you'll catch on rock stations) they're like std's, I assume. F&ck you, mainstream.
