It’s tempting to lump the former frontman of teen R&B sensations B2K in with the herd of mono-monikered Usher wannabes. But as the fans who lofted O to No. 1 last week could tell you, there’s more to Omarion Grandberry than that. The ballads on this solo debut have way too much whipped cream, but there are some surprisingly tough touches of funk and crunk (”Drop That Heater,” the Missy-esque ”Take It Off”). And ”Growing Pains” is a farewell to his former bandmates that’s actually kinda touching.
