If the hip-hop game tested emcees for illicit substances the way the MLB screens players for performance-enhancing drugs, I have a feeling there would be a lot fewer rappers. One of the first out the door would be 2 Chainz, who proudly compares himself to currently-suspended Yankee A-Rod on this freshly-released promo single, a cut previously performed live on his 2 Good 2 Be T.R.U. tour. Over Young Chop's trunk-rattling production, the A-Town hitmaker emphasizes his penchant for “smoking that strong” and alludes to his former career “[running] base.” Bad Boy hitmaker French Montana lends his flow to the final verse, and Sharod Marcus Simpson directs the non-work-safe official visuals. (Keep your eye out for a cameo from Wale.) A-Rod isn't attached to a larger project, but we'll keep you posted on Chainz's 2014 plans as further details emerge.
