"Tactics ogre: Let us cling together" on PSP is a remastered version Tactics Ogre - tactical jrpg for SNES. Besides all the remastered stuff it has reorchestrated soundtrack, which is glorious.
The music is composed by Hitoshi Sakimoto and Masaharu Iwata, so it's reminiscent in style to music from Final Fantasy Tactics and Final Fantasy XII
I enjoy listening it on the regular basis very much. apparently, it is sold standalone, but I couldn't find it anywhere except iTunes https://itunes.apple.com/us/album/tactics-ogre-let-us-cling/id402622164
it is also available with premium edition of the game
Here are some of my personal favorite tracks:
