Jay-Z: When you think of Jay, you think success, not mistakes. But he hasn't batted 1.000: he was put on probation for three years in 1999 after a scuffle with record executive Lance "Un" Rivera. Even worse: he recorded an EP with nu-metal band Linkin Park in 2004. Kanye: There's just not enough space to go over Kanye's many gaffes. Whether he's snatching the microphone from Taylor Swift during an acceptance speech or claiming the president doesn't care about black people, Kanye knows how to stir up controversy.
