The album's songs are characterised by metronomic rock-inherited pop, vocal harmonies, hand claps, prominent electric guitar riffs, bright synthesizers, double entendres for sexual intercourse, a homogeneous sound and message, the pitch-correcting software Auto-Tune, and rotations of lead vocals [REF].
Alexis Petridis, a music journalist, interpreted its signature sound as a "peppy, synth-bolstered take on early-80s new-wave pop, heavy on clipped rhythms and chugging guitars," which, he said, is at least an improvement on the substitute R&B "that was once the grim lot of the boyband."[REF]
