 The movie is based on an idea by Mariah Carey (qv) that kept  bouncing back from studio to studio starting in 1997, and the singer  began writing songs for the soundtrack album prior to the movie even  getting a green light. Carey admits that when the project was  approved for production (2000), she found songs for the movie that  she had written and forgotten about. She was only supposed to do six  songs, however many collaborations with current and 1980s producers,  writers, and artists including Jimmy Jam (qv) &  Terry Lewis (III) (qv), and the late Rick James (II) (qv) led to  growth for her track listing, which became the entire soundtrack. A  song by her and Prince (I) (qv) was also in development, but it  did not make the deadline in time for soundtrack reproduction,  packaging, and distribution.
