Kanye West has pissed people off in all sorts of crazy ways, but nothing riled up the public quite like his upstaging of Taylor Swift at the 2009 MTV Video Music Awards. Judging by the fierce reaction, one might think he shiv'd her in the stomach as he left the stage as opposed to just briefly grabbing the mic in a stupid, drunken stunt. Kanye dealt with the blowback by yanking a planned tour with Lady Gaga and heading to Hawaii to begin work on his fifth album. He obsessed over every note of My Beautiful Dark Twisted Fantasy, and "Power" was no exception. Built around a sample of King Crimson's 1969 classic "21st Century Schizoid Man," the song displays Kanye's intense resolve in the face of overwhelming negativity.
It's also a favorite of Emerson, Lake and Palmer's Greg Lake, since he's the lead vocalist on "21st Century Schizoid Man." Each show of his ongoing solo tour kicks off with this song.
