Jason Derulo

Jason Derülo has jumped headfirst into the world of contemporary R&B with a swagger and a keen understanding of pop-song dynamics like a man in it for the long run. His singles \"Whatcha Say\" and \"In My Head\" spin his pleading vocals against club atmospherics and stripped-down, post-*808s & Heartbreak* minimalism. He also shows a knack for self-promotion that can\'t be disputed.

The former Lil Wayne songwriter has made an efficient, sometimes infectious, but impersonal debut, says <strong>Caroline Sullivan</strong>
