Just some comments about the arrangers of this album...
I strongly believe that TERRA here is this one
https://vgmdb.net/artist/1106 ... specially after looking at a cached version of the website daichimusic.com (listed in the booklet) where the MintJam logo can be seen after following the link enter:

https://web.archive.org/web/20070102...-2/HP/top.html
MORRIGAN seems to be
https://vgmdb.net/artist/1153, based in a cached copy ( see:
https://web.archive.org/web/20130315...gan/index.html ) where he links to the Feline Groove Label and so on. Some works hints to it.
And that is all... I can't figure out the other ones with what I can understand.
This is, to see if it is appropiate to have them then linked. Unless someone has anything that contradicts what I have found.
