If you thought Morgan Wallen had a lot of songs on his last album - the 19-week Billboard 200 chart-topper One Thing at a Time - the country superstar is ready to do you one better on his upcoming fourth album I'm the Problem.

Wallen has proven he can bring the party with his uptempo anthemic tracks, but he can just as easily slow things down for a ballad. "Sand in My Boots" is a nostalgic, heart-tugging song that reminisces on a love that could have been. Hardy wrote the track alongside Josh Osborne and Ashley Gorley.
