November 8, 1971 ~ Led Zeppelin IV is released. It includes “Stairway to Heaven” which is pretty much the perfect rock song – so good that many fans feel there are other forces at play. When played backwards, it sounds something like “my sweet Satan,” so perhaps it was the Devil who was moving the pencil when the words arrived. The rumor spreads throughout high schools across America, becoming one of the great urban legends in musical history. The song is never released as a single and therefore doesn’t chart, but it becomes the most-played song in the history of FM radio.
