that sometimes is buried and hidden because I'm working so hard, and I don't have time to think about it. But if we sit down and we talk about it and I tell her how I feel and she writes, it'll be good." Several producers and songwriters who did not contribute to Metamorphosis worked on the album, including Andreas Carlsson and Desmond Child ("Who's That Girl?"), British songwriter Guy Chambers ("Shine"), Julian Bunetta and James Michael ("The Getaway") and Ty Stevens ("Rock This World"). Ron Entwistle is co-writer and co-producer of "Weird", which Duff said is "about someone that she's still obsessed with. And everything he does is like he says this, but he does this ... She's not really sure who he is or what he does, but she likes it." Kevin De Clue contributed to "The Last Song" and "Mr. James Dean" (both co-produced by Haylie), which Duff has named her favorite track on the album and described as "very funny"; in the song, she tells an ex-boyfriend that he'll "never be James Dean." Duff neither confirmed nor denied whether the song was about fellow singer Aaron Carter, and she said "it was definitely an experience that I went through that was interesting and I learned a lot from that time in my life." In "Hide Away", co-produced and co-written by Shaun Shankel, Duff discusses a relationship that isn't working because she is in a position where her life is "figuratively under the microscope." Diane Warren wrote "I Am", an empowerment song in which Duff lists positive and negative aspects about herself; she has said it is about being comfortable "with all those feelings ... being who you are." David Campbell arranged and conducted strings for the tracks "Someone's Watching Over Me" and "Who's That Girl?". Duff's management team considered recording a song titled "Since U Been Gone" for the album, which Lukasz "Dr. Luke" Gottwald and Max Martin had originally written for Pink.

"Since U Been Gone" was later recorded by Kelly Clarkson, for whom it became a major hit. Singles "Fly" was the lead and only single with a music video from the album. It is also the only single released in the US. The music video directed by Chris Applebaum, combines black-and-white backstage footage with
