Good Girl was written by Dustin Lynch and two other friends of his. Apparently Dustin Lynch at the time was single when this song was being written but his other buddies were happily married. “It’s a song I wrote with two guys that have their lifelong partners, but I was the guy in the room who didn’t, so, yeah, I sing that song from longing to find that person that sets my world on fire and takes life to a new level”, Dustin Lynch says.
