6. Rage Against the Machine, 'Killing in the Name'
Rage Against the Machine released "Killing in the Name" as their debut single in 1992, showing their unique fusion of rap and rock from the very start. It's a furious song about racism, police brutality and defiance, culminating in a furious cry of "Fuck you, I won't do what you tell me." It has the power to stir up a crowd like virtually no other song in human history, and it served as the final encore at what could very well go down as their last concert.
