After getting approached by the filmmakers of Hannah Montana: The Movie, Swift agreed to have her music featured on the film's soundtrack. Not only did she cowrite the film's ending number (performed by Miley Cyrus as Hannah Montana) with Boys Like Girls lead singer Martin Johnson, but she also makes a small cameo in the movie to sing her country song "Crazier."
