Yoko Shimomura, the composer of the music for the Kingdom Hearts series among other titles is also writing/composing the music for Final Fantasy Versus XIII. Releasing March 26, 2008 she has compiled a CD of her "Very best work" for her 20th anniversary.

It seems as though her Very Best Work CD will come with a Final Fantasy Versus XIII "bonus track" according to HMV.JP. The CD will also include tracks from Kingdom Hearts, Front Mission, Secret of Mana.

We're hoping that it's the full version of the only trailer music which has been hear so far in Final Fantasy Versus XIII which you can listen to here. A full version would of course be longer and higher quality without the sound effects from the trailer.

Since they are able to release a track so early, can we assume that the soundtrack is now finished?
