The music of the vieo game series Kingdom Hearts was composed by Yoko Shimomura with orchestral music arranged by Kaoru Wada. 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, including such songs as "Mickey Mouse Club March" by Jimmie Dodd, "This is Halloween" by Danny Elfman, and "One-Winged Angel" by Nobuo Uematsu. They also features 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.
