But the band's current single is not only being played on the radio. It was recently featured in the Vince Vaughn film, Delivery Man, a promo for MLB Fan Cave and a Lowe's commercial that aired during the Super Bowl.

"I think with any art, it's just putting yourself out there and hope people can connect with it," guitarist and banjo player James Adam Shelley said. Many have found a connection with the feel good vibes of "Best Day of My Life" where the guys sing about living it up. They're touching the clouds, howling at the moon and just generally grabbing life by the balls, singing, "No limits just epiphanies."

The guys seem to have a knack for writing anthems including their debut single "Believer," which urges fans to look optimistically towards the future. "In the verses it's talking about all these flaws and insecurities that we have as people," singer Zac Barnett explained. "It's saying, 'I'm sheltered, I'm scared, I'm nervous that I'm not getting anywhere. I'm jealous and I'm slow. But at the end of the day, these are the things that make me who I am.' When the chorus hits, it's 'I'm a believer that things are going to get better.' You can be who you are and stay true to yourself, but in the end things are always going to get better in life."

This is a motto American Authors have taken to heart. The guys met at the Berklee College of Music in Boston through various songwriting clubs and classes and decided to leave school early and move to Brooklyn to pursue music full time. It wasn't always easy, but the early struggles help make them closer as a unit.
