Not a Collectors Edition or anything but there's an actual Ni No Kuni Soundtrack
if anyone's interested. I think it comes out to $35 with shipping. The website is in French but the soundtrack booklet is in English.
Comes with 2 discs (33 tracks) and a 20 page booklet. There's 870 available as of this posting and I think it's exclusive to that site. When I checked a couple days ago there were 921.
