DROPKICK MURPHYS!!! Greatest band ever! I listen to them about 7/8ths of the time when I've got music playing, I'm listening to them right now as a matter of fact.

But when they aren't in the CD player (which is VERY VERY rare) I listen to just about everything else; country, metal, death metal, rap, even bluegrass. It just depends on what kind of mood I'm in. Some other bands I like are Slipknot, Powerman 5000, Cradle of Filth, Disturbed, Metallica, Outkast, Ludacris, Chingy, Nelly, Hank Jr., Rascal Flatts, the list goes on and on. About the only thing I can't stand to listen to are the boy bands.
