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.
