Someone I Used To Know - Petey Radio Remix

Zac Brown Band's first new song since their 2017 Welcome Home album finds Zac Brown reflecting on finally being able to move on from the person he used to be in favor of becoming the one that he actually is. It's been a long time comin' Couldn't keep on runnin' Had to hit rock bottom to know When you keep on losin' with the path you're choosin' Then it's time to let go Of someone that I used to know The song was written by Zac Brown Band with Canadian pop star Shawn Mendes. The collaboration came about following their hookup in September 2018 on CMT's Crossroads, the music channel's concert series that pairs country stars with artists from a different genre.

Zac Brown Band performed the song for the first time during the November 9, 2018 episode of The Tonight Show Starring Jimmy Fallon.

Zac Brown explained at the end of the song's music video that "Someone I Used to Know" is a reminder that people "don't have to be alone in what they feel." He added that he has a personal connection to its theme of moving on from the person he used to be. "This song is me facing that part of myself, of where I want to go and not where I've been," Brown said. "I would encourage people that when they feel they have a need, or they have a voice that's telling them to face something, it's a sign of strength to ask for help and to face the things that are really hard. That's what defines you: Overcoming those things."
