How's Paypa been spending his time since stepping into the Booth with Serenity, the inaugural song release off his next street album, this past July? Unsurprisingly considering the man actually named himself after money, the Chi-town representative has been “Grinding like a motherf**ker,” to get that currency. On this freshly-minted street single, the rhymesayer offers listeners a window into his ceaseless hustle, describing his intense regimen of recording, performing and boob-signing over Vinylz' smoldering synths and trap percussion. Brooklyn buzzmaker Troy Ave assists on the guest tip. Digging it? Then don't miss the rest of the fresh cuts set to appear on Paypa's Kim Jong Ill tape, due out Wednesday, December 12.
