The soulful 'I'm Going Down' was written and produced by Norman Whitfield, known for his seminal work with Motown in the '60s. Unlike many other songs that are used in movies only after they become hits, this one was first performed by Rose Royce on the soundtrack for the 1976 film 'Car Wash' -- and it got a whole new audience when Mary J. Blige covered it almost two decades later.

In 1995, Blige changed the song title to 'I'm Goin' Down' and included it on her breakthrough second album, the intensely personal 'My Life.' Thanks to heavy radio airplay (remember radios?), it wasn't long before the success of her cover surpassed that of the original, with the track reaching No. 22 on the Billboard Hot 100 and No. 13 on the Hot R&B Singles chart.

Today, it's still one of Blige's best-known songs, and she frequently includes it in her live sets.
