Trouble

"Trouble" sits on *Obsession* as its slickest and most physically confident track — where the title song is cold, this one is warm-blooded and sleazy in the best way. The groove is funk-leaning R&B: a bass guitar high in the mix playing an actual line rather than a synth sustain, muted rhythm guitar chips on the offbeats, and drums that swing just enough to make the pocket feel human. It's one of the few EXO tracks where you can hear players rather than programming. The vocals lean fully into breath and falsetto — Baekhyun's runs decorate rather than dominate, Kai's low delivery works as a rhythm instrument, and D.O.'s tone anchors the choruses with a soul-record roundness. The lyric is flirtation as a knowing risk, calling someone trouble while making it obvious that's the appeal, and the Korean writing keeps a light comic self-awareness that keeps it from sounding predatory. Within the group's discography it belongs to the "Ooh La La La" / "Damage" lineage of body-first B-sides that carry the album's pleasure while the title track carries its concept. It's music for getting dressed to go out, or for a small apartment kitchen at midnight with one lamp on and nobody watching.
