15. Yung Joc "It's Goin Down" (2006)
Album: New Joc City
Label: Bad Boy South, Block Entertainment, Atlantic Records
Although his ATL predecessors T.I. and Young Jeezy were certainly accessible, Yung Joc was the first bubble trap rapper, setting the stage for swaggier and more cartoonish figures to follow. When he says "Meet me at the trap, it's goin' down," he sounds so ebullient and welcoming that he may as well be inviting you down to the neighborhood malt shop to join in a round of milkshakes. But nothing was goofier than Joc's motorcycle dance, immortalized by Tom Cruise, that was arguably as much a viral component of the song's success as that catchy hook.
