Dirt Road Anthem by Jason Aldean. Colt Ford and Brantley Gilbert wrote this song at the Gilbert's house in Georgia; the song first appeared on Ford's 2008 debut album Ride Through the Country, and Gilbert included it on his 2010 LP Halfway to Heaven. It was the first tune that the country artists wrote together.
