FNAG-0014: BROKEN THUNDER PREVIEW DISC

[JumboMaverick]

Didn't even know FNAG-0014 existed... but I saw it on Ebay:

...and the only tracklist I could manage to find is here:

Does anyone have any more information on this release?

Preview Disc was distributed through Toranoana, starting on Feb 24 2007. The game itself came out in May that year.

Google translation:
CD-Extra specification.
By Shanxi Toshiharu and Tsukumo Momotaro, recording three songs BGM the music track.
The data track, 20 points a CG image and high resolution movie promotion of "Broken Thunder", recorded in the MP3 BGM on the CD track further.

(Also it mentions Toshiharu Yamanishi on that page so added him to composer field, just like he is for the OST CD)

Some places say it was distributed for free, like this one: http://19xx-s-rank.seesaa.net/article/34611249.html
No idea what it means being distributed for free... anyone could place an order on the website while supplies lasted?
