“I remember with ’Don’t You Want to Stay?’ Kelly was actually my first choice for that song and I’ve just always been a fan of her voice. And then when you get on stage or in the studio and start trading vocals with them, it’s like, man, you realize really quick that who the better singer in the room is, you know what I mean? Those guys are amazing singers and really powerful and just a lot of range. It’s really cool for me to get to work with people like that and sort of find my spot in the song to make my voice work with theirs and it’s been great.

I mean, obviously Kelly, the song we did with her got us a Grammy nomination and just was a really big song for us, single of the year at CMA’s. Hopefully, we can replicate that with this song,” he had said.
