My music tastes swing wildly depending on what mood I'm in. I've been on a real "Dave Matthews Band" kick lately -- I still think Before These Crowded Streets
would be my one "stuck on an island" CD.
Old favorites: Oasis, Jurassic 5, Dropkick Murphys, Counting Crows, Dispatch, Ben Folds Five, Flogging Molly, Toad the Wet Sprocket, Outkast, Audioslave, O.A.R., Carbon Leaf, and the immortal Wu-Tang Clan.
Eclectic -- but I've never been one to limit myself to one particular genre of music. It's how you end up with an iPod that can go from Miles Davis to Method Man on shuffle.
