I've heard that this game's OST is remastered version of the PSX's soundtracks.If is that true,i want this game's soundtracks

As I own FF Tactics: The Lion War, I can safely say that is not actually the case.

The soundtrack is identical to the PSX version in every way, although there might be a couple of extra tracks for the extra battlefields that were added in the new version. I'm not sure though.

is anybody know where we can download the new ost for final fantasy tactics...?
