9. Bob Dylan, 'Hurricane'
Bob Dylan was a decade past his protest song phase when he became aware of Rubin "Hurricane" Carter, a professional boxer in jail for a murder he claimed he didn't commit. With help from playwright Jacques Levy, Dylan wrote an impassioned eight-minute tune about Hurricane's ordeal, dramatically raising public awareness of the situation. Dylan didn't exactly get all the details right and was even taken to court by witness Patty Valentine over alleged inaccuracies, but the song remains incredibly powerful. Even so, he hasn't performed it a single time since 1976.
