"My Sweet Passion" is the theme song of Amy Rose, used in Sonic Adventure, Sonic Adventure 2, Sega Superstars Tennis, the end sequence of Sonic and the Black Knight (as "The King's Peril" on the game's soundtrack), and plays during Amy's All-Star Move in Sonic & Sega All-Stars Racing and Sonic & All-Stars Racing Transformed. An instrumental version of part of the song replaces the music when using the Amy Rose 3DS Theme. It was performed by Nikki Gregoroff.
