Trey Songz likes sex. But he loves sex farce. On his third album, this smoothie from Virginia — one of R&B's nimblest vocalists — takes cues from R. Kelly, slyly mocking the self-parodying excesses of boudoir R&B while supplying the utilitarian goods: the sumptuous vocal harmonies and sultry beats upon which long nights beneath ceiling mirrors depend. Songz enrages his neighbors with loud "bangin'"; boasts, "I invented sex"; and explores the erotics of emoticons in what may be the year's best-titled song, "LOL :-)." The "Purple Rain"-like power ballad "Yo Side of the Bed" shows that Songz can be awfully good when he plays it straight. But he's great when he delivers the LOLZ.
