Everyone loves Maroon 5, and much of their success is due to lead singer, Adam Levine. Levine’s smooth, beautiful voice with ridiculous range is definitely a fan favorite. When he’s not on tour with Maroon 5 or performing shirtless at Super Bowl halftime shows, he can be found as a coach on The Voice.
