"Certified Diva"'s beats and chorus follow the auto-tuned electro-pop slant practically dictated by the subject matter (witchy vamping in the mold of Rihanna) but dancehall starlet Tifa's gruff, take-charge patois levels it out, and Akon protegee Tami Chynn's low-voiced bridge ups the ante. It's interesting to see the different directions the Badda Badda Gals are taking their careers—as Tifa appears to head in a pop direction, Natalie Storm's latest was a crushing bashment track, while Timberlee's sticking closer to her pared down digital dancehall.
