Vybz Kartel may be the most convincing vocalist in dancehall. On ferocious battle tracks like "Empire Army", his voice clangs like a tank engine. But when he sings euphoric love songs like the billowing synth jam "Half On a Baby", he becomes a crooner smooth as Sinatra, relating his affairs in exacting detail with Auto-Tuned glee. Born in Jamaica, Kartel crossed over to U.S. charts with tunes like 2009's X-rated "Romping Shop". Here, over an R&B-influenced beat, he and deejay Spice explicitly describe every moment of a heated sex session—and make it all sound surprisingly romantic.
