Well, according to what CDJapan has written up, that piano cd doesn't have to do with FFXI at all.
Here's what I got in my email today:
"Price: Yen- 10476, US$(87.22) Release Date: 28-Mar-2007
Soundtrack box set release from hit online game "Final Fantasy XI"
includes the original 2-disc "Final Fantasy XI Original Soundtrack"
album, "Final Fantasy XI Jilart no Genei - Original Soundtrack,"
"Final Fantasy XI Promathia no Jubaku - Original Soundtrack," and
"Final Fantasy XI Treasures of Aht Urhgan: Original Soundtrack"
releases plus two bonus CDs: an unreleased collection of tracks from
the game performed by opera star Izumi Masuda and the hit "FFIX Piano
Collections" release. Box set includes all seven discs plus the
complete piano sheet music for the "FFIX Piano Collections" album."
I don't know what other FFXI stuff Izumi Masuda has done, but she did do the song "Distant Worlds" which is the ending(?) theme to Chains of Promathia.
The track is included on this cd, which Uematsu composed the music for.
I don't know about any of you, but I'm bummed to hear this.
I never had bought the FFIX piano album, but I never expected it to be a bonus in this collection, and I sure don't need any sheet music for it.
Smells to me like S.E. is getting lazy.
