"I'm pissed off that he gave 'Payback' to Rascal Flatts," Johnston confessed, pointing to Mason. "He never played it for us. I would have done that. But we'll talk about that later."

It's hard for Johnston to complain too much about his bandmate giving good songs away, since he's still kicking himself for giving Keith Urban the Eric Church-assisted track, "Raise 'Em Up."

"At the time, as soon as I got done with it I was like, 'I gotta send this to Keith,'" Johnston said. Urban immediately liked what he heard and cut it that week. It wasn't until months later, when Johnston took the stage with Urban at the ACM Party for a Cause event in April in front of 20,000 people that he realized what he had given away

"I took Eric's part and I was like, 'S-t,'" Johnston said. "It really clicked, I could sing that song every night."
