Who Do You Love (ft. 5 Seconds of Summer)

This track operates in The Chainsmokers' most commercially confident mode — crisp, wide, radio-engineered to feel like forward motion. The production is built around a driving four-on-the-floor kick, layered with bright synth arpeggios that never become abrasive, and a drop engineered to feel inevitable rather than surprising. 5 Seconds of Summer's Luke Hemmings anchors the verses with a voice that carries enough pop-rock grain to give the otherwise pristine electronic production some friction — a deliberate roughness that signals authenticity within a polished frame. The song is about the peculiar anxiety of attachment, specifically the vertigo of caring about someone while being uncertain if that care is returned in kind. It doesn't wallow in that uncertainty; instead it channels the feeling into momentum, which is the track's defining emotional strategy — propulsion as a substitute for resolution. This is peak-era streaming pop built for motion: morning runs, highway driving, gym playlists where the tempo matches the effort. The Chainsmokers understood that their audience wasn't looking for nuance so much as a large, clean feeling delivered efficiently, and this song delivers that contract faithfully. The collaboration makes structural sense because 5SOS had been migrating toward synth-pop for years, so neither act is operating outside their comfort zone.
