Miranda Lambert and HARDY performing a heart-wrenching unreleased new song, titled “Dog Years,” at “Music For Mutts,” a Miranda Lambert's MuttNation benefit concert. HARDY, a songwriting mastermind, wrote the poignant new song from the perspective of a dying dog and throughout the track he details the bittersweet bond between a dog and its owner. #MirandaLambert #HARDY #DogYears | Music Mayhem
