With the NBC reality competition's return just a month away (Monday, Sept. 22 at 8/7c), Levine doesn't underestimate the impact the past six seasons have had on his life, both professionally and personally. "The show has changed my life in a profound way," Levine says in the exclusive behind-the-scenes video below. Levine has done seven seasons in three years, all while juggling his duties as the lead singer of Maroon 5 with his blossoming acting career. Despite the busy schedule, it doesn't sound like Levine will give up his big red chair anytime soon.
