The riff came to Keith Richards in a dream one night in May 1965, in his motel room in Clearwater, Florida, on the Rolling Stones' third U.S. tour. He woke up and grabbed a guitar and a cassette machine. Richards played the run of notes once, then fell back to sleep. "On the tape," he said later, "you can hear me drop the pick, and the rest is snoring."
Two decades later, Jagger admitted that "Satisfaction" was "my view of the world, my frustration with everything."
