The album’s lead single, “I Had Some Help” features Morgan Wallen, and rode up to the top of the Billboard Hot 100 and Hot Country charts. The rapper and singer has spent the last few months on the country circuit to solidify his yee-haw bona fides, including performances at the CMAs and the Grand Ole Opry.
