Jason Derulo jumped into contemporary R&B like a man in it for the long run

Jason Derulo 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.
