Duff said that she had been working with brothers Joel and Benji Madden, of the American rock band Good Charlotte, and Jason Epperson (together known under the production name the Dead Executives) to write and produce new songs for the compilation. She said that " ... they're three of my favorite songs I've ever done. ... It was really fun being in the studio with them." Described by Duff as the first time when "all the responsibility was on [her]", she went into the recording studio without the guidance of her record label or management.

The Dead Executives were instrumental in the instrumentation of "Beat of My Heart", performing on the bass and guitars. They also mixed and engineered the song; the latter was also conducted by Todd Parker and Grant Conway and assisted by Allan Hessler. It was mixed and recorded at the Foxy Studio in Los Angeles, California. The drums featured on the track was performed by Dean Butterworth while Monique Powell and
