833. Black Magic Woman by Santana (1970)

Peter Green of Fleetwood Mac wrote "Black Magic Woman", but the song did not achieve classic status until covered by Carlos Santana. As a result, people forget the Mac version while the song is closely associated with Santana. In fact, the cover helped Santana's Abraxas go quadruple platinum. The Santana version now appears on Guitar Hero.
