Genres are putty in the hands of superior song man J.R. Rotem. His instinct for slick R&B steers Plies' "Bust It Baby, Pt. 2" into cool, sleek anthem territory. And Rotem banks just as neatly off pop history, sampling Ben E. King's "Stand By Me" for the yearning, reggae-inflected "Beautiful Girls" and pulling the gothic nostalgia of Soft Cell's "Tainted Love" into Rihanna's stomping, unapologetic "SOS".
