1. One who gets in our way. Epic and really goes well with most the game's scenes. This should be the game's main theme.

2. Gaur plain: One of the best field soundtrack i had ever listen to.

3. You will know our names. The best battle theme ever created. it is so energetic and dramatic, makes you realize things are getting serious and at the same time encourages you to battle.

4. Engage the enemy. Just awesome.

There are other ones that are good too like the one in satorl marsh and valak mountain, but these 4 are the bests. The soundtrack in this game is just incomparable.
