The fifth single from upcoming relaunched version of Rihanna's runaway third album "Good Girl Gone Bad" may sound on the surface like a sweet ode, but the teen singer is actually ridiculing her man's unconvincing apology after he's nabbed cheating. She offers, "Don't tell me you're sorry cuz you're not/You're only sorry you got caught/That was quite a show, very entertaining, but it's over now/Go on and take a bow." With superstars Stargate and Ne-Yo at the helm, the velvety ballad ticks along with well-applied piano and strings, as the instantly recognizable singer delivers a convincingly bemused vocal, complete with haughty laugh. Rihanna has been an unstoppable presence since she burst to the top with "Pon De Replay" in 2005; 10 singles (and an armload of Grammy Awards) later, she's still gaining speed and worthy of a "Bow." —Chuck Taylor
