i would like the Crystal Chronicles (gamecube) OST if possible
the DS games (ring of fates, echoes of time) ost would be nice too if anyone has those

I'm not sure if the 1st soundtrack is here on the shrine, but just checked those lossless thread and found:
FINAL FANTASY CRYSTAL CHRONICLES A Musical Journey (http://vgmdb.net/album/7426)
Trypetide's rip here: http://forums.ffshrine.org/f72/lossless-video-game-soundtrack-thread-v2-126974/221.html#post2662017

and
FINAL FANTASY CRYSTAL CHRONICLES Ring of Fates Original Soundtrack (http://vgmdb.net/album/4583)
CBGS's rip here: http://forums.ffshrine.org/f72/lossless-video-game-soundtrack-thread-v2-126974/57.html#post2350135

Now, I do know that bakabt has a huge Final Fantasy music collection torrent going. You could always go find that, and just check the albums you wanted to grab and ignore the rest. I'm pretty sure that most, if not all the crystal chronicles albums are on there.
That should be enough to get you started. Enjoy.

I have the Crystal Chronicles OST in V2 MP3. If that's high enough quality for you I could send you a link.

Edit: Since posting, I found it in FLAC, so you can have it in any format you want, really.
