Four years after breaking up, two millennials meet again in a hotel bar and rekindle their romance in the back of a Range Rover, even though nothing’s changed between them. That’s the basic plot of “Closer,” the poppy 2016 future bass earworm that gave both The Chainsmokers and special guest Halsey the first No. 1 hit of their careers. Chainsmokers singer Andrew Taggert says “Closer” was inspired by Blink-182 and Taking Back Sunday, which explains the dark emo vibes hanging over this hookup scenario.
