"Swinging London Town" received critical praise. It was called "a dark, squiggly synth pop epic a la Pet Shop Boys on the diverse characters – from wannabes to trustafarians – found in the nation's capital", and that there "hasn't been a song since the Pet Shop Boys' 'West End Girls' that captures the ugly charms of London on a Friday night, but 'Swinging London Town' comes close." It was further described as "a collision of warp-speed funk guitar riffs and distorted Giorgio Moroder-style techno-disco that unexpectedly drops into wafting movie-soundtrack ambience." "It's Magic", a Nicola Roberts solo which was called "the album's hidden highlight", was labelled "weighty, sultry electro-pop [...] layered with beautifully enticing synth melodies." "No Regrets", sung solely by Nadine Coyle, is an electro-bossanova ballad. The album's closer, "Racy Lacey", is "a portrait song of a young lady in the style of Prince's "Darling Nikki" or Blur's "Tracy Jacks." "The Guardian" called it "a kind of nuclear-powered Euro novelty record."
