"I was diagnosed with a kidney stone and through the pain I was delirious on some sort of drug, pain medication," he told Radio.com. "My tour manager said I was singing that song through my stupor and pain so I knew at that point that was going to be the single. I called our manager the next day and said this was going to be our single and that was that."

Anderson added that "Hearts Go Crazy" was also selected as the first single because it was so versatile, with the band recording several versions of the song so it could translate to any genre.

"We had the acoustic version, we had the rock version, we had a pop version, we even had a house/dubstep version," he said. "It was a very nice vehicle to get our sound across all these different spectrums. It's definitely different from what we've done but the song itself is overall us."
