41. "Black Magic Woman"
Fleetwood Mac's first Top 40 single in the U.K. was written by Peter Green after he'd seen a scary play on TV. "There's a whole group of skulls and things," he recalled. "It was so frightening." On "Black Magic Woman," he set that imagery to scruffy white-boy blues. The song might have become an obscurity had it not been for Santana's hit remake two years later, which adhered to the original Mac arrangement. (The idea came from Santana keyboardist Gregg Rollie.) When Fleetwood Mac were inducted into the Rock and Roll Hall of Fame in 1998, Green was on hand to play "Black Magic Woman" live with Santana.
