What Do You Mean?

The harmonic vocabulary here is deliberately lean — four diatonic A♭ major chords repeated throughout, with no modulations or borrowed chords. The track's distinctiveness comes from placement rather than content: syncopated steel-drum-adjacent melodic loops, off-beat chord stabs, and a half-time feel in the verses create rhythmic tension that the simple major-key harmony keeps from feeling cluttered. In the tropical house genre, this restraint is a feature, not a limitation.

Bieber, Jason 'Poo Bear' Boyd, and Mason Levy wrote 'What Do You Mean?' around the theme of romantic mixed signals. Bieber later confirmed the song was about his relationship with Selena Gomez, describing the subject to Ryan Seacrest as 'flip-floppy — they say something and they mean something else.' MdL, who had produced Bieber's 'Boyfriend' in 2012, helmed the track again. The rollout itself became part of the song's story: on August 19, 2015, Bieber direct-messaged different lyric lines to 49 randomly selected Twitter followers, each paired with a clock animation marking the lyric's position in the song, turning the campaign into a fan-assembled puzzle.

Released on August 28, 2015, as the lead single from his fourth album Purpose, 'What Do You Mean?' marked a sharp stylistic pivot for Bieber — pairing a buoyant tropical house beat with lyrics about romantic ambiguity. Produced by MdL at 125 BPM in A♭ major, it topped the charts in seven countries and sparked a commercial comeback few artists of his profile had managed after a public rough patch.
