When Brad Paisley brought out opening act Riley Green to share the stage on the latter's new song "I Wish Grandpas Never Died," it was a big moment for the Big Machine artist/Warner Chappell songwriter, whose debut full-length, Different 'Round Here, drops on 9/20.

But you get the feeling that the song isn't going to need much help; it's one of those heartfelt singalong jams that, after one listen, feels like you've known it forever. The troubadour performed it at a show mere days after it dropped and the whole freakin' crowd was singing it at the tops of their lungs.

Riley's seen a huge spike in followers on Spotify (with an attendant boost in monthly listeners), Instagram, Facebook and YouTube. Check out the studio version below.
