"... these pop poindexters are so adept at producing standalone hits that releasing an album feels like a formality. This second album has already spawned five singles, including three No 1s. Still, hearing these songs side by side does helpfully expose some of Clean Bandit's methods. While their 2014 debut, New Eyes, was built around pop-house and string-section flourishes, What Is Love? draws opportunistically on more recent chart trends, namely Latin pop and diluted dancehall. It also sees the band continue their teamwork-based approach to music-making. Each track sports at least one starry guest, be it Demi Lovato or Craig David - something that happens to be a reliable indicator of chart success (collaborations make up around one-third of hit songs)".
