Utada Hikaru’s newest song, Passion, is also the theme song to the upcoming Kingdom Hearts II, which yours truly is very much looking forward to. The PV starts off animated, then moves to Utada Hikaru singing in hallway and in a circular room, and ends with horses and her in a wide open field. This is a pretty high budget PV, and I particularly enjoy the animation portions. After listening to this a few times, I can definitely see this being a theme song. That being said, it’s very different from Hikari of the original Kingdom Hearts. The way she sings Passion give the song an almost ethereal quality. It all depends on how the producers of KH2 decide to use it.
