The original soundtracks of the games have been released on three albums and a fourth compilation album. The soundtracks to the Kingdom Hearts games feature several musical pieces from both Disney films and Final Fantasy games, including such pieces as "Mickey Mouse Club March" by Jimmie Dodd, "This Is Halloween" by Danny Elfman, and "One-Winged Angel" by Nobuo Uematsu. They also feature several vocal songs, the most notable being the two main theme songs, "Hikari" and "Passion". The two themes were written and performed by Japanese American pop star Hikaru Utada. "Hikari" and "Passion" were originally in Japanese, but English versions were also produced, titled "Simple and Clean" and "Sanctuary", respectively.
