The official theme song to Final Fantasy XIII was officially unveiled a Square Enix's private party a few days before this year's Tokyo Game Show. It is sung by Sugawara Sayuri and is entitled Kimi Ga Iru Kara. It's also composed by famed Final Fantasy composer Nobuo Uematsu.

Up until now, only a sneak preview of the song had been heard, but we can now offer a full mp3 download of the song, which was played on Japanese Radio.
