Donors got a flac version a while back while we waited on the cd.  Supposedly they have shipped but I have not received.  Again I am not familiar with the source work but was very happy with all but one track which felt out of place.  Personally I think it is better than the Grandia album.

This is what I have so far:

13 Sentinels: Aegis Rim Original Soundtrack BSPE-1091~4
CHRONO CROSS 20th Anniversary Live Tour 2019 RADICAL DREAMERS Yasunori Mitsuda & Millennial Fair Live Audio at NAKANO SUNPLAZA 2020 SBPS-0041~2
FINAL FANTASY VII REMAKE Original Soundtrack ~special edit version~ [Limited Edition] SQEX-10768~75
FIRE EMBLEM PREMIUM ARRANGE II QWCI-00007
G-LOC AIR BATTLE -Series Music Collection- WM-0787
HEAVY METAL RAIDEN INTERNATIONAL CD INCD-E0118~9
SQUARE ENIX Chill Out Arrangement Tracks – AROUND 80's MIX SQEX-10793
SQUARE ENIX JAZZ -FINAL FANTASY VII- SQEX-10744
The Legend of Zelda: Link's Awakening Original Soundtrack COCX-41117~20
TRIALS of MANA Original Soundtrack SQEX-10783~5

Of those, the only one I've listened to multiple times is FIRE EMBLEM PREMIUM ARRANGE II QWCI-00007 (nothing is going to surpass this). I haven't listened to any of the others in full, though all of them are interesting.
