I like a LOT of music... I guess it's mostly alternative... my favorite radio stations are all the alternative ones. But I like a lot of different stuff... from Stevie Nicks to 3 Doors Down (who I got to meet at a concert!) to Joni Mitchell to Jimmy Eat World. But VERY little country (I'm not a fan of twang), absolutely no rap, no christian music (except Dashboard Confessional, but I don't really consider them religious in any way), and no teeny bop stuff or boy bands (uck, I can't stand them!). I don't like Avril Lavigne much... I think it might be due to overexposure. She and her songs are EVERYWHERE and it drives me crazy now.
Currently, I love listening to Jimmy Eat World, Dashboard Confessional, Guster, Sarah McLachlan, Stevie Nicks, Counting Crows, U2, Norah Jones, etc etc. I could go on all day. I live for music.
