"From a small town of Tullahoma, Tennessee [Lynch's hometown], to five No. 1s in a row at country radio … this song has never felt bigger and our crowds have never been better. The fans are the reason for my success, so thank you to every single person who turned this song on, turned it up and sang it at the top of their lungs at one of our shows."
