studio album Dangerously in Love, recording up to 45 songs. After the release of Dangerously in Love in June 2003, Beyoncé had planned to produce a follow-up album using several of the leftover tracks. However, on January 7, 2004, a spokesperson for her record label Columbia Records announced that Beyoncé had put her plans on hold in order to concentrate on the recording of Destiny Fulfilled, the final studio album by Destiny's Child, and to sing "The Star-Spangled Banner" at the Super Bowl XXXVIII in Houston, Texas, which was a childhood dream of hers.

Beyoncé kept the recording somewhat quiet, telling only her artists and repertoire executive Max Gousse, and the team of producers they contacted to collaborate with on the album. She began working with songwriters and producers Rich Harrison, Rodney Jerkins, Sean Garrett, Cameron Wallace, the Neptunes, Norwegian production duo Stargate, and American hip hop producer and rapper Swizz Beatz. Two female songwriters, who helped structure the album, were
