“Part Time Lover” by Stevie Wonder

Stevie Wonder led off In Square Circle, his 20th studio album, with "Part Time Lover" in 1985, a cheating song with a sting in its tail: a man stepping out on his wife learns at the end that she's been stepping out on him too. Wonder wrote and produced it, with Gary Olazabal as associate producer, played the drums and synthesizers himself, and later called the music an ode to two songs by his Motown labelmates the Supremes, "You Can't Hurry Love" and "My World Is Empty Without You".

Luther Vandross throws in the ad-libs, with Syreeta and Philip Bailey of Earth, Wind and Fire among the backing singers. It topped the American pop, R&B, dance and adult contemporary charts, making Wonder the first artist with a number one on four different Billboard charts, and it drew a Grammy nod for Best Male Pop Vocal Performance.
