Pretty much anything I know by heart and can sing along to works for me. I just shuffle my "Top Rated" playlist all day and try to add at least a few new songs to it every so often. It's a pretty big mix, with everything from Zero 7 to MF Doom to David Bowie to Gravity Kills to Johnny Cash, Oasis, Dr. Octagon, Lemon Jelly, Hole, and a ton more.
