Nas is back with yet another track off his upcoming album, Life Is Good. And like preceding leak "Accident Murderers," this cut also features the Queensbridge O.G. trading verses with a guest rapper. This time, it's NYC stalwart Large Professor, who shares the No I.D. production here. Life Is Good, which drops July 17, just keeps on sounding better and better. Stream "Loco-Motive" below.
