Jason Derulo's gift for infectious, floor-filling anthems made him a star, but a darker ripple to his artistry lurks underneath those glossy hits. “Cheyenne” rides a pulsing electro-pop groove that takes the Florida singer back to the neon-pink ‘80s cool of Miami Vice, while the woozy synth nightmare of “Naked” recasts him as a scorned lover trapped between unrequited lust and a bitter grudge.
