If you were to mash up the All-American Rejects and Imagine Dragons you would come up with the American Authors. At least that is the way I feel about their single “Best Day of My Life,” an incredibly catchy, feel good, sunny side up type of song that is today’s SOTD. American Authors hail fromNYC and are the latest signee to Island Def Jam who has gained success on the pop charts. Although the band considers themselves an indie band, they have tons of pop elements in their music. “Believer” is another one of their singles that leads me to this belief as well as the songs on their debut album, Oh What A Life. But at the end of the day these guys are talented and due to the success of “Best Day of My Life,” expect to hear from them all summer long.
