The song is "just one of my favorite tracks" from Two Lanes of Freedom, McGraw told Radio.com in an interview earlier this year. It's got a groove that he called "breezy" and "funky," noting that the song "has this laid-back feel" but that "there's an intensity to it as well."

"Southern Girl" is the fourth single from Two Lanes of Freedom, coming after his recent No. 1 smash "Highway Don't Care" (which featured Taylor Swift and Keith Urban) as well as two songs released last year — "Truck Yeah" and "One of Those Nights."

"Southern Girl" was written by Jaren Johnston, Rodney Clawson (who also cowrote "One of Those Nights"), and Lee Thomas Miller.
