Nickelback, Default, Linkin Park, Good Charlotte, Blink 182, the Strokes, Evanescence, Brittany Spears, Slipknot, Marilyn Manson, System of a Down, Disturbed, and many more I'm not thinking of right now.

Edit: Jesus, yes, Metallica. The new stuff, anyway. Shouldn't they be pulling their heads out of their asses sometime soon?
