First premiered whilst on tour with the Jonas Brothers in Las Vegas back in November, 'Gut Punch' is a reflective ballad which sees Nick get vulnerable about becoming his biggest critic. "Hit me like a gut punch. I hurt my own feelings. How did I get so good at being mean to myself?" he sings, as he explores the pressure of personal expectations.
