I have this horrible feeling, the same feeling that I got from seeing the Red Dwarf movie listed under Danny John Jules's filmography on the Blade 2 DVD. Perhaps it's just having waited for so long for Final Fantasy Versus XIII, but I can't help but feel that this DLC, available for download in Japan now, is jinxing things a little bit.
Announced earlier this week, Somnus is the theme song from Final Fantasy Versus XIII and is now a downloadable addition to Theatrhythm: Final Fantasy. Whether it's a tease for some upcoming announcement is yet to be seen, but this is about as close as we've yet to come to a playable version of the game. We couldn't have seen it coming when Versus was originally announced.
Still, it's a nice song and it'll be a pleasure to play it when Theatrhythm finally releases in the west later this year.
