Aloud, giving the former group an "urban feel" and the latter a "punky [and] guitar-led" sound. Following the success of Girls Aloud's first four singles, Xenomania was enlisted to produce Girls Aloud's second album, What Will the Neighbours Say?, in its entirety. Higgins said, "The pressure to come up with singles was, as always, immense. But [...] we were able to have a lot of fun working on ideas that were maybe a little too odd to be on the radio." The Guardian hailed Neighbours as "a great album: funny, clever, immediate, richly inventive." Stylus Magazine declared, "There is no pop in the world like Girls Aloud today." All four of the album's singles ("The Show", "Love Machine", "I'll Stand by You" and "Wake Me Up") were top five. Xenomania were approached to work with Australian pop singer Kylie Minogue on new tracks for her greatest hits collection Ultimate Kylie, including the single "Giving You Up", which developed a reputation among her fans as one of her worst singles. Other Xenomania productions proved less successful. Mania was a joint venture between Higgins and BMG. The duo, consisting of Xenomania songwriters Giselle Sommerville and Niara Scarlett, released one single before being dropped. The boy band V, whose single "Hip to Hip" was produced by Xenomania, was short lived. Higgins called V "bright and motivated, with a lot of charisma [...] When we decide to work with an artist it is normally a decision based on personality and the challenge we feel it holds for us". 2005–2007: Critical acclaim Higgins and Xenomania were once again given free rein for Girls Aloud's third album, Chemistry. The album's second single, "Biology", was critically acclaimed, being called "the best pop single of the last decade". Despite the group's near total obscurity in the United States, the song was listed at number 245 on Pitchfork Media's "The Top 500 Tracks of the 2000s" list. It was also listed at number 23 on The Observer Music Monthlys 75 best singles of the decade. Chemistry was praised by critics upon its release. BBC Music decided that the album was "quirky, modern and dripping with attitude" and "holds no disappointments." Virgin Media gave the album five stars, saying it was "bursting [...] with invention, quirky lyrics, tongue-in-cheek sauciness and [...] appeals to grown-up pop fans and music critics as well as to the teenyboppers."
