Maybe you like your New Yorkers a bit grimier. "Shmoney Dance" has been blowing up on Vine and Twitter quite organically, although a brief Kevin Durant cosign portends further cosigns, an ensuing wave of hype, and-yep-Rowdy Rebbel and Bobby Shmurda are outta here. Of course, it won't be without an attendant controversy. (And that's before you get to Bobby Shmurda's solo cut over Lloyd Banks' "Jackpot," "Hot N****," now approaching half a million views.) Accusations that this is manufactured by evil forces to bring down rap from the inside are no doubt gearing up as we speak. But even in the unlikely event that this record was contrived in a label office, the illuminati overlords have managed to capture very potent lightning in a bottle.

Despite production from Philly's Jahlil Beats, the aesthetics is post-Chicago drill. Even the song's name seems a mutation of the "Money Dance," also known as "Dro Style," popularized by Lil Mouse--although the Shmoney dance itself bears no resemblence. That seems the m.o. here. Chicago slang and style (for example, Rebbel raps about being "with the shits") popularized by artists like Chief Keef and Lil Reese reached a tipping point to youth street culture nationally, and has become the language new artists use to describe their own situations, a snake shedding its skin. Through creative misprision, it's coming out New York-ified—a long chain of influence running from hip-hop's birthplace in New York to Atlanta, up North to Chicago and then back East. New York seems particularly desperate for relevance now; it should be no surprise that this is being snapped up so quickly.

The Shmoney dance itself doesn't seem to be a specific dance; instead, the two rappers seem to be making it up as they go, gripped by the music, expressed with exuberant confidence. Rebbel and especially Bobby Shmurda seem so self-possessed on camera, their bodies moving with contagious self-assurance. But most importantly, it's fun, and vibrates with the urgency of the moment.
