The Matrix, a record production team consisting of Lauren Christy, Graham Edwards and Scott Spock had "just come off the back of a very successful little run" with three number one hits with Avril Lavigne when Disney approached them and asked if they would be interested in writing for Duff. They agreed and called Midnight, who had already been involved in the project. Christy cited him as one of her favorite writers and her mentor. Being familiar with their work, meeting with The Matrix was "very exciting" for Duff. Upon hearing the demos for "So Yesterday", "Where Did I Go Right?" and "The Math" – performed by Christy – Hollywood Records "immediately loved them".
