Yea, there's like a handful of tracks for the 2 new dungeons, a couple cutscenes etc. on the PS3 version.
There are apparently no official releases containing them.

I was wondering if anyone ripped them or could rip them. Please? Pretty please?

I have the EZI battle theme and the EZI dungeon theme that I ripped, Quality isnt so hot thanks to ripping them with an analog output cable from my HDMI input. But if you want those I can upload them. (The quality isnt HORRID, just a little static)

That would be great. Apparently the theme of the Lament Mirror is on the game's HP.
If you could record the other missing tracks (the game luckily has the sound test), I'd be INCREDIBLY grateful.

Edit:
I ripped Lament Mirror's theme from the site... it's, unfortunately, pretty bad quality (128kbps). Nothing better available (should anyone be interested in downloading it: http://www.mediafire.com/?ryzdgzj2jzx ).

As said, if you could rip the missing music directly from the game's sound test (you can use the vgmdb-entry to check which are not on the OST: http://vgmdb.net/album/4631 ), and maybe name them according to said sound test, I'd love you to pieces.

Chopin is one of my favourite composers when it comes to Classical, and Sakuraba is one of my favourite VGM composers, and the music of Eternal Sonata is just beautiful. <3
