Girls Aloud by Louis Walsh until 2005 when Hilary Shaw replaced him. The new group competed with the boys' winning group, One True Voice to have 2002's Christmas number one single. Girls Aloud won the battle with their single "Sound of the Underground", produced by Brian Higgins and Xenomania. The song spent four consecutive weeks at number one and was certified platinum in March 2003. The song received critical acclaim; Alexis Petridis of "The Guardian" stated that "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".
