9. "Don't Stop the Music" (2007)
It's a global dance-pop smash, produced by a couple Norwegian guys (Stargate) that hits a high point referencing a historic vocal line from a 1983 Michael Jackson classic ("Wanna Be Startin' Somethin'") that was itself a reference to an early-Seventies jam from Cameroon (Manu Dibango's "Soul Makossa"). In other words, classic Rihanna: effortlessly gathering the whole world into her vision of sweat-caked, face-to-face, hands-on-your-waist disco elation. She asked Jackson's permission to borrow the iconic "Mama-say, mama-sa, ma-ma-ko-ssa" hook for "Don't Stop the Music" and the resulting song ended up being a massive global hit, with a video in which RiRi breaks through a secret door in the back of a candy store into a crazy club where she shakes her stress away.
