“Call You Mine” is the fourth single of the year for The Chainsmokers, and features Bebe Rexha as the lead vocalist. The song comes as part of the gradual release of the World War Joy album.

The song talks about a young, fading relationship built with uncertainty between both partners as to whether there is hope in their relationship, with consideration as to where their lives would lie without each other.

The Chainsmokers and Bebe Rexha collaborated in 2014 for the remix of “I Can’t Stop Drinking About You.” One year before, the American duo remixed “Take Me Home” by Cash Cash, where Bebe Rexha was featured. However, this single marks their first direct collaboration as primary artists on a song.
