Crisis Core had so many awesome battle themes, its hard to pick which one is my favorite, they were all so cool >.

the one i posted in perticular is my favourite Random battle theme , i remember first playing it it got me pumped up espicially that scene where they talk about "Using it brings wear and tear" and the bomb wents off at the same time as that music starts.

Oh man I remember that part, it was pretty awesome. Man, now I'ma have to beat the game again.

Isn't Final Fantasy the only JRPG series you played? :P

Also - Ito is good and all and imma let you finish, but Mitsuda wrote some of the best OSTs of ALL TIME.

He is my favorite for writing any type of music other than battle themes, the best guy for that is Sakurba, he wrote Tales of the Abyss, Valkyrie Profile, Baten Kaitos, check him out :P

My favourite JRPG composer is Shoji Meguro. But, he isn´t much known, like Uematsu. His work is pretty different from Uematsu, but IMO fits games perfectly.

Some tracks, may contains spoilers.
