"Change" is a midtempo pop rock ballad composed of anthemic harmonies, guitars, keys and sweeping effects.

The band performed the single during an acoustic gig as part of Radio Clyde's Up Close series, and on The Paul O'Grady Show.

"Change" was co-written and produced by the Danish production duo Deekay, composed of Lars Halvor Jensen and Martin Michael Larsson.

[11] It contains anthemic melodies backed by a powerful 1980s guitar lick,[12][13] and incorporates the group's harmonies into keys and sweeping effects.

[5] The song's lyrics are about the experiences of change after the departure of a close friend and ultimately never being the same again, but the need to remain strong in the process.

[19] The single's accompanying B-side is titled "I Can't Take It No More",[20] and was composed by the Sugababes, Jeremy Shaw and Jony Rockstar.

Sunday Mail critic Mickey McMonagle called "Change" the album's best track and "a definite chart topper".

[12] Alex Fletcher from Digital Spy and the BBC Chart Blog's Fraser McAlphine rated the song four out of five stars; the former regarded it as a "sophisticated pop ballad" and highlighted the Sugababes' vocal abilities,[5] while the latter described the chorus as "anthemic".

[11] In contrast, a writer from The Scotsman considered it "vapid",[22] while a critic for Manchester Evening News felt that the group's vocals were average.

[23] Tom Young of BBC Music wrote that "Change" "only flirts with credibility" due to the group's "irrepressible and watertight harmonies".

[26] "Change" spent 14 weeks on the chart,[26] and had sold 95,000 copies in the UK by April 2010, making it their 15th highest-selling single in the country.

[38] It then cuts to Berrabah, who is shown with long eyelashes and large red and yellow blooms in her hair, to represent summer.

[39] To promote the release of "Change", the Sugababes performed the single during an acoustic gig on 12 December 2007 in Scotland, as part of Radio Clyde's Up Close series.

[40][41] The group performed the song on The Paul O'Grady Show the following day,[42] and on BBC Switch's entertainment programme Sound on 15 December 2007.
