I'm generally a fan of the slow music, moreso.
Genres would include Indie, Funk, Techno/Trance, and anything sad, haha.
Bands would include Death Cab For Cutie, Appleseed Cast, Mars Volta, Red Hot Chili Peppers, Muse, Stark Raving Calm (Local Band, i mention because I listen to them SOO freaking much.) Cake, Everclear, Filter, Incubus, Modest Mouse, Moby, Mogwai, Pink Floyd, Pavement, Pixies, Smashing Pumpkins, Perfect Circle..... Haha, the list could go and go and go.
And from time to time (parties, mostly) I love MSI.
My biggest rules are no current age rap (I like alot of the old stuff before angry rappers started talking about how hard life in the "hood" is. To which I have a feeling most of them have never even been in the "hood".) and under no circumstances do I tolerate country.
