Utada Hikaru, Japan's better and more intelligent alternative to the West's Brittany Spears and co. Aside from actually being liked by people, she has the ability to actually do a lot more than merely sing. For her song "Simple and Clean" from Kingdom Hearts, she not only sang but did the basic programming as well as writing the song. She also assisted producing and arranging the piece, which says a lot for her talent.
Titled "Passion", the single will no doubt sell well over in Japan. It will be interesting to see if she then translates her song into English, just as she did for "Hikari" (light).
Either way, it's good to see she's back for KHII, and this song adds to an ever growing list of things that makes this game look very sharp indeed.
