in pop music as it was." "Sound of the Underground" received critical acclaim, with The Guardian exclaiming it "proved a first: it was a reality pop record that didn't make you want to do physical harm to everyone involved in its manufacture." The song was the Christmas number-one of 2002, selling just over 213,000 copies in its first week of release. The single spent four consecutive weeks at number one, achieving a platinum certification from the British Phonographic Industry. "Round Round" and "Sound of the Underground" have been called "two huge groundbreaking hits", credited with reshaping British pop music for the 2000s. The Telegraph placed the latter song at number 15 on a list of 100 songs that defined the 2000s, while NME included it at number 39. In 2003, Xenomania wrote and produced "No Good Advice" for Girls Aloud, which reflected Higgins' general mood of failure after the deal between Xenomania and London Records fell through. Shortly afterwards, Higgins heard the other tracks that Girls Aloud had recorded for their debut album Sound of the Underground and was dissatisfied with the obscurity and inconsistency of the group's direction, and personally intervened to produce four more original tracks for the album to replace some of the weaker content. Shortly after the album's release, another round of sessions during that summer yielded three new tracks that later surfaced on a reissue of the album in November, including a massively successful cover version of The Pointer Sisters song "Jump" for the film Love Actually. It was said that "Higgins injects an element of instant-catchy-cool to the songs without going overboard in trying to shape uber-chic dance floor hits." Also that year, they produced the singles "Miss Perfect" and "7 Ways" for former Five member Abs's solo album, Abstract Theory. Sugababes' "Hole in the Head", another UK number-one, was one of several tracks for their album Three that were co-written and produced by the Xenomania team. According to Higgins, he knew "Hole in the Head" was "the single" as soon as he heard the backing track again: "Those moments of clarity are the best bit about the music business. We try to find perfect matches unique to the artist we are working with". Cooper—who recalled being "scared" of Sugababes because of their heavy involvement in the songwriting process—said that Xenomania made a conscious effort to differentiate their Sugababes work from that of Girls
