Music video
The music video was released on March 25, 2019. In the music video, the Chainsmokers perform in a Battle of the Bands against 5 Seconds of Summer. They play in comparison to see which band is the best. The two bands start performing in a concert. In the bridge, 5 Seconds of Summer frontman Luke Hemmings crowd surfs, before the Chainsmokers member Andrew Taggart does the same, jumping from the stage roof. In the end, the stage explodes because of the tension between both bands.
