“All I Know” is a posthumous R&B-flared remix of Biggie’s 1999 release “Come On” that describes a struggle to leave behind a life of crime.

Though the track was scrapped from Biggie’s 2005 posthumous album Duets: The Final Chapter, the instrumental and Akon’s vocals were eventually repurposed for Beanie Sigel’s 2012 album This Time, taking the title “That’s All I Know.”
