Found a japanese Tracker...

[Yume]

Hmm.. I found a japanese Torrent Tracker. I'm to 100% sure, they have also VGM there. Problem is the language... but hey. If anyone got to much time (like me XD) he/she'd like to invest in a little treasure hunt. Welcome!
Hmmm.. its probably more or less random downloading but we may find stuff which never makes the way to the USA/Europe.
In case anyone got something special, please post it with your opinion, to make someone else's hunt easier. I'll do the same...
Then.. lets see x_X *starts random loading*

They've got mostly anime, and in the music section only anime OSTs, as far as I have seen...
If I were you, I'd limit the hunt for soundtracks to the music section (fourth sorting option from left)
