"What a Girl Wants" is a song by American recording artist Christina Aguilera, taken from her self-titled debut album (1999). A re-recorded version was released on November 28, 1999 by RCA Records as the second single from the album, following the commercial success of the lead single "Genie in a Bottle". The song was written by Shelly Peiken and Guy Roche. After the pair were improvising lyrics with a cassette recorder, Peiken decided to return to it at a later date. The song was completed and pitched to RCA executive Ron Fair as "What a Girl Needs" and was renamed "What a Girl Wants"; Fair later gave the track to Aguilera. A Spanish version of the song, titled "Una Mujer," was included in Aguilera's second studio album Mi Reflejo (2000).
