The album opens with "Intro", a 42-second introduction, The end of "Intro" segues into the first full track on the album, "Models". The song "deals with men who try to assert their masculinity by sleeping with cover girls", but contains a "council estate girls made good" sub-text. It received comparisons to Duran Duran's "Girls on Film" (which Girls Aloud once covered) and Madonna's "Material Girl". One reviewer called "Biology" "the most faithful to this album's spirit of innovation, blending the kind of saucy cabaret you'd expect to find in a gin-soaked saloon bar with a glorious chorus of fizzing, gliding synths and deceptively breakneck beats." "Wild Horses", track four on the album, "features a mock choirgirl intro segueing into a breezy acoustic-rocker [...] like a harder St Etienne." It was also described as "a futuristic country & western club banger". The song is followed by "See the Day", a cover of the 1985 Dee C. Lee single which has been "given a glossy 21st century refurb". The version, described as "the obligatory Christmas ballad", was largely slated for its lack of creativity and similarities to their 2004 cover of The Pretenders' "I'll Stand By You" (although some critics preferred it).
