Producer: Missy Elliott

Missy Elliott landed her first No. 1 hit in 2001 after producing the Moulin Rouge! cover of Labelle's "Lady Marmalade." Revisiting classics to make fresh hits must have stuck in her mind when she sampled Mtume's "Juicy Fruit" for Keyshia Cole's "Let It Go" in 2007. But there's absolutely no way any hip-hop fan can hear that break and not smile and think of The Notorious B.I.G.'s all time classic "Juicy," so naturally Lil Kim was invited to rhyme on the record. Although the song was about letting failed relationships go, it still felt like a bit of tribute to Big Poppa, especially when Kim shouts out "Baby baby!" in her best Biggie impression. —Insanul Ahmed
