Just to rattle off a few names as they come to mind:
Queen, Mannheim Steamroller, Johnny Cash, Guns and Roses, Burl Ives, The Beatles, Elvis Presley, Weird Al (White and Nerdy, BTW, is like a bloody themesong for me despite the fact that I've never done most of that stuff), Rossini, Schooner Fare.
I tend to shy away from newer stuff, but I recently dug out my old X-Files movie album, which includes Foo Fighters, Tonic, Filter, The Cure, Sting and more. Also, a coworker made up a disk for me to listen to which included Rasputina, Rammstein, Seraphim Shock and some other artists I can't think of at the moment.
Some kinds of music I just can't get into include modern classical (prepared pianos and composing with TV static...just not my stuff), heavy metal (I feel like the music is made to be loud so that the band can cover up that they stink) and excessively violent rap.
