There's a new song on country radio right now, from Florida Georgia Line and the Backstreet Boys. It's "God, Your Mama and Me."

But the duo still can't believe what happened with their last single, the ballad titled "H.O.L.Y."

"I think we knew it would connect, but we make these plans and we think they're big and we dream these dreams," FGL's Brian Kelley said in a recent radio interview.

"And God's like, 'Nah, I got something way bigger in store. Let me do my magic."

Kelley and Tyler Hubbard think that's what happened with "H.O.L.Y."

"It's something so much bigger than Tyler and I," he said, "and that's why it is so special and it's beyond our control and it's magical."

When they perform the song live during shows, it turns into something of a religious experience.

"Every night we have church up there onstage, and it takes us to a place that we've never really gotten to go in our show," Kelley said.

"It's a different dynamic and you see people worshipping out there, you see people cryin', dancin', fallin' in love again. And it's a beautiful, beautiful thing. We're so thankful for that song. We know the power of a song."
