The things that have kept Usher in the firmament of safe, dependable R&B stars are not strictly musical — that smile, those abs and his slick dance moves are pretty irresistible no matter your persuasion. While he's never been much for innovation, this year's Raymond v. Raymond proves that even when he coasts, Usher can still pump out sexed-up club jams. "OMG" lives up to its vapid title with a guest spot from an Auto-Tuned, but "DJ Got Us Fallin' in Love" — which has trancey synths, clattering beats and his high-flying love call — fares better as sure-fire dance-floor fodder. At this week's performance, expect plenty of crooning from Usher — and an equal amount of swooning from his devotees.
