I listen mainly to electronic music. Breakbeat, trance, house, and DnB are the ones that hold my attention the longest.
Of course, I enjoy most other genres. Right now, I am listening to Bad Religion and Finger Eleven.
And on a sour note, I have a gig tomorrow for a sorority. Lots of girls = good. Playing R&B and hip-hop for hours = bad. Hip hop and country are really the only two genres of music I don't like.
