6. 'I Wish'
Stevie Wonder looks back on his childhood when he was "a little nappy-headed boy" in his 1976 Number One hit "I Wish." The song kicks off the second side of Songs in the Key of Life, and (much like Sly Stone's "A Family Affair") was composed on a Fender Rhodes electric piano. Will Smith sampled the song on his 1999 track "Wild Wild West" and even played it with Stevie Wonder at the MTV Movie Awards. It did little to save the movie, though, which was an absolute flop.
