Muse. My favorite song of theirs is Hysteria. I seriously think they fuck it up when they play live. Last two times I heard it live from different places, the guitar solo seemed off-key and too high-pitched than normal.
Tupac Shakur. Musically, there's nothing I dislike about him. I do dislike the fact that he was shot, though. But seriously, there's nothing I actually dislike about him.
