Hilary Duff had always wanted to follow in the footsteps of her elder sister, Haylie. Duff watched her sister rehearsing in 2001, after which she told her mother that she wanted to be involved in singing.
During the same time period, Duff attended a Radio Disney concert where she met Andre Recke, whose client Myra was performing. According to Duff, watching the pop musicians preparing and warming up backstage at the concert made her think, "I want to do this so bad".
Recke said he thought Duff, who was popular with preteens at the time because of her role in the popular Disney Channel original series Lizzie McGuire, had "something special ... Sometimes you just have that feeling, that, 'Wow, she's a star.'"
After becoming determined to start a music career, Duff resumed her vocal lessons—which she had started before her acting career began—and became one of Recke's clients.
Duff said, "I've always had a big drive. When I felt like something looked fun or I wanted to accomplish something, I really just go for it ... I didn't really know what it was gonna be like, but I knew I wanted to try it and I knew that I could do it."
Duff recorded several songs for Disney soundtrack and compilation albums, and a Christmas album "Santa Claus Lane" in 2002.
Her songs "I Can't Wait", "Why Not" and "What Dreams Are Made Of" were hits on Radio Disney, but Recke and executives at Buena Vista Music Group envisioned Metamorphosis as a vehicle by which Duff could reach a more mature audience.
Duff, her mother Susan, and Recke enlisted the songwriting and production team The Matrix—whom Recke had previously hired to write songs for Myra's 2001 eponymous debut album—and songwriter Charlie Midnight (who had contributed to "Santa Claus Lane").
According to Duff, her mother, Recke and Duff herself worked very hard to get music that she related to and was age-appropriate for her.
Duff said that she did not want to make "a really poppy album" because that was not the type of music she listened to.
The presence of The Matrix was noted because of their work on Avril Lavigne's highly successful debut album "Let Go", but Duff said that she did not want to emulate other artists, saying: "There are definitely people I respect and I love their music, but there was never really an artist that I said, 'I want to be just like them...' ... I wanted to be like myself".
According to Duff, although she did not write most of the songs, she collaborated on each of them.
Aside from The Matrix and Charlie Midnight, contributions to the album came from singer-songwriter Meredith Brooks, Kara DioGuardi, Matthew Gerrard, John Shanks and Duff's sister, Haylie, who Duff said knows her better than "anyone else in the world".
Duff discussed her feelings with some of the songwriters, and she praised them because they were open to her opinions and "really got it". She said that she would have liked more time to work with the songwriters and co-write more of her own material, saying: "I feel like you need time to really get in touch with yourself to do that".
In May 2004, Meredith Brooks (writer and producer of "Party Up") complained about the million-dollar budgets major labels spend to produce albums, saying: "There's something seriously wrong with all that! You can't keep that going. Artists have to sell millions of records for anybody to make money off of those bloated budgets."
