Kingdom Hearts: RE Chain of Memories IN GAME OST

I already know that the OST for this game has been released, but if you listen to the tracks in game while played as opposed to the ones released on the CDs, they sound noticeably different. I’m looking for in particular the in game versions of Graceful Assassin, Scythe of Petals, and Lord of the Castle, not the official, released versions. If anyone can provide a rip or a link to them I’d be very grateful. The in-game versions sound so much better.

For instance, this is what I mean.
