From "Pon Di Replay" and "Rude Boy" to "Man Down," Rihanna always likes to rep her island roots with each album, and Unapologetic is no exception. This reggae-flavored tune was produced by No I.D. and written by Elijah Blake, the man behind Usher's "Climax." It's all about a love that comes on stronger than a gunshot. "Like a bullet your love hit me through the core," she sings.
