Two years isn't long, but the world of R&B has shifted since Trey Songz's 2010 album Passion, Pain and Pleasure, thanks to Frank Ocean's wild experiments and Usher's EDM-R&B fusions. Trey seemed primed for a similar creative breakthrough with 2011's promising EP Inevitable, but he's reverted to formula on Chapter V. That's not a bad thing when it comes to sex-drenched bedroom jams like "Dive In," "Heart Attack" and "Playin' Hard." However, avoid the unintentionally disgusting swag rap "Check Me Out," where he claims "I took her panties and I put a pool in it."
