Beat of My Heart

"Beat of My Heart" is a song recorded by American actress and recording artist Hilary Duff for her compilation album Most Wanted (2005). Duff co-wrote the song with the Dead Executives, who helmed the production of the song. The song was created with Duff's intention of wanting a "totally different sound" than her previous works. "Beat of My Heart" is about gaining self-confidence and is composed as an electropop song that incorporates elements of bubblegum pop and dance music. "Beat of My Heart" serves as the second single from Most Wanted, receiving its first commercial release in Australia and New Zealand on December 11, 2005.

"Beat of My Heart" received mixed reactions from music critics, many of them criticizing it for being repetitive and childish while others gave it credit for presenting an easy-to-listen-to sound. The song was a moderate success on several international charts, peaking inside the top ten in Italy and the top twenty in Australia and Spain. It failed to achieve success in Switzerland, peaking in the lower half of the singles chart. The music video for the song features Duff in a series of vignettes inspired by opening title sequences of James Bond films, and sporting different looks inspired by the different eras of the Bond films.
