“Signs” point to a new Luke Bryan track dropping on Friday. “Get ready for September and pre-order your copy now,” he closed the post. “Signs” follows his #12 hit “Country and She Knows It,” which sits right beside his #11 duet with George Birge, “Ride, Ride, Ride,” on the country airplay chart. His tour namesake, “Word on the Street,” plus “Fish Hunt Golf Drink” and “Made it a Memory” have already come out as well. The full Signs will be posted Sept. 17.
