Music Box: Let me rock ya, Chaka

Chaka Khan broke out in the mid-70's with funk pioneers Rufus ("Tell Me Something Good") and went on to a successful solo career with hits like "Ain't Nobody", and "I'm Every Woman" The latter, famously covered by Whitney Houston, proving that the exact same song can be a hit in two different decades.

To celebrate the soul diva's birthday, this is "I Feel for You." Written by Prince, the song originally appeared on his 1979 self-titled album, and was Chaka's biggest hit in 1984. The opening rap, by Melle Mel, was one of the first bits of hip-hop flavor to find it's way to the suburbs -- a full two years before Run/DMC broke through with "Walk This Way."
