Stevie Wonder, "Superstition" (1972)
"Fingertips Pt. 2." became Stevie Wonder's first Number One hit when the soul wunderkind was just 13 years old, but despite a dynamic string of Sixties singles, he didn't top the charts again for nearly a decade. This clavinet-driven workout established the one-time child star as the adult genius who would dominate the decade: As with Marvin Gaye's "What's Going On," "Superstition" was the sound of a Motown artist taking control of his career. And Stevie's hit was just as political in its own subtle way as Marvin's, channeling the mood of skepticism prevailing in the U.S. at the time.
