I like lots of styles of music I suppose. I hate country but that one song by the chick from american idol about a guy cheating on her is hilarious.
Anyways, I like instrumental/art rock bands the most such as Godspeed You! Black Emperor, Mogwai, And You Will Know Us By The Trail Of Dead, Murder By Death (if you like these bands, EMAIL ME!! I don't know anyone outside of my little group of friends who has even heard of them!!)
a little classic rock like the Doors and Pink Floyd
alternative rock like The Smashing Pumpkins and Nirvana
mopey whiney music like Bright Eyes, Jeff Buckley, Fiona Apple, The Postal Service, Neutral Milk Hotel, Rufus Wainwright, The Smiths
industral and hard rock like NIN, Tool, Manson and I LOVE Rob Zombie
and a little punk rock and cabaret punk music... like the Sex Pistols, Rancid, The Dresden Dolls
and lastly, something about Justin Timberlake... what a talented guy
