10. Teena Marie & Rick James - "Fire & Desire"
The early Eighties was a ripe time for smoldering R&B duets between stars in the making, with radio stations specializing in love songs of the smoother variety sprouting up all over the country. This seven-minute chronicle of ex-lovers looking back at their past lives together, which appeared on James's 1981 full-length Street Songs, was never released as a single, but it lit up R&B radio. Marie and James had collaborated previously — he co-produced her 1979 debut Wild And Peaceful — but the way the two wind around each other on this particular track is pure, well, fire.
