Utada Hikaru is releasing another single on Dec. 7, reports Bounce.com. The title track of the single, “Passion”, serves as the theme song for the video game Kingdom Hearts II. A limited edition CD+DVD release hits stores Dec. 14.
“Passion” will be the fourth single Utada has released since her last Japanese language studio album, Deep River, in 2002. Three or four pre-release singles is usually a sign an album is in the works, but now that Utada is juggling both English- and Japanese-language careers, who knows what’s in the works?
