I tried to rip the music from the games, but it is impossible. So I like to request a gamerip or something.

just in case anyone ever is interested in this too, it seems the composer allows the legal free download of it:
Robb*Mills | The Spiderwick Chronicles (http://robbmills.com/?portfolio=spiderwick-chronicles)
(i never actually played the game so i dont know if this is the 'complete' soundtrack)

Wow, thanks so much for that link. I thought I would never find this available.
