23. "Pour It Up" (2012)
Produced by Mike Will Will Made It, "Pour It Up" finds Rihanna flexing like a boss in the strip club, tossing dollar bills at the exotic dancers. "Money make the world go round/Bandz make your girl go down," she growls. In the process, she toys with gender roles. As is often the case for an artist whose music-video savvy rivals Madonna and Beyoncé, the song's salacious video extends that concept into a beguiling fantasy: She plays both stripper and john, going from working a pole to twerking on top of a gold throne, all while smoking a cigar.
