All over the place. My tying playlist includes everyone from Chevelle to Charlie Daniels, from AC/DC to A cappella, from Beastie Boys to bluegrass, from Linkin Park to Lady Gaga. I even have two hardcore rap songs and one classical piece. About the only things missing are jazz, dubstep, Bieber and any country music made in the last 15 years (except Red Solo Cup).
If I am on Pandora it is usually "Mumford and Sons Radio" or "Black Keys Radio"
