"Don't Hang Up" and "The Answer", which appeared on the North American edition of the CD of Britney Spears: In the Zone, originally appeared as bonus tracks on international editions of In the Zone (2003). Spears wrote "Don't Hang Up" along with its producers Brian Kierulf and Josh Schwartz, while "The Answer" was written and produced by Sean Combs and Ryan Leslie.[2] The tracks were replaced by the Bloodshy & Avant-produced "I've Just Begun (Having My Fun)" and Linda Perry-written and produced "Girls and Boys" on the international edition of the video. Both were originally recorded for In the Zone but failed to make the cut. "I've Just Begun (Having My Fun)" initially appeared as a bonus digital download on the Walmart exclusive edition of In the Zone, before being included on Spears' first greatest hits albumGreatest Hits: My Prerogative in November 2004.[3][4]
In November 2003, Billboard announced that Spears planned to release a video album with previously unreleased footage in mid-March 2004.[5] On February 26, MTV reported that the video would concentrate on the live performances to promote In the Zone (2003), such as her performances of "Me Against the Music" and "(I Got That) Boom Boom" on Total Request Live and the half-hour surprise appearance at the Palms Casino Resort's Rain Nightclub.[6][7] Originally set to be released on March 23, Britney Spears: In the Zone was later pushed back to April 6, and was released as a DVD+CD set.[7][8]
The DVD of Britney Spears: In the Zone also included her American Broadcasting Company (ABC) concert special of the same name, which had aired on November 17, 2003. Filmed at the Gotham Hall in New York City in October, the show featured stage settings evoking Cabaret. The video also contained the accompanying music videos for "Me Against the Music" and "Toxic", alongside the latter's episode of Making the Video. The North American edition CD included "Don't Hang Up" and "The Answer", whereas international editions included the tracks "I've Just Begun (Having My Fun)" and "Girls and Boys".[7][9][10]
Britney Spears: In the Zone received mixed reviews from critics. Aaron Beierle of DVD Talk highlighted the concert special, but said that the interviews and behind-the-scenes footage "are geared clearly towards promoting the album and, while they achieve that goal, they break up the momentum of the concert terribly." He summarized his review by saying: "In the Zone does disappoint somewhat with the audio, but the video quality is good. Recommended for fans."[6]
