Stevie Wonder's career reached a new level in 1972 with the release of Talking Book. He was just 22, but he was already a veteran artist with 15 albums under his belt. He was enjoying a greater creative freedom, and a tour with the Rolling Stones introduced him to a new audience. The album has many of Wonder's most beloved works ("Superstition," "You Are the Sunshine of My Life") and it wraps up with the eternally optimistic "I Believe (When I Fall In Love It Will Be Forever)." It's one of the simpler songs on the LP, and one of the most beautiful.
