1.) Bright Waters. I really like the way this song meshes well with the corridors leading to the Veil. All those long, peaceful tunnels leading ever up towards the light with this playing in the background, building to a slow, gentle crescendo. You know something fantastic and joyous is up ahead.
2.)Li's theme. And here's the culmination of that joyful anticipation. This music makes it feel like everything is going to be all right for Naija from now on (it's not , but that's how you feel when you hear it at least).
3.) Fallen Breed. A real "rock opera" piece. You just KNOW you're on your way to kick some ass!
4.) The part of "Worship" that plays during the Creator's Final Form. Perfect climax music.
5.)Heart of the Forest. One of my favorite parts of the game has always been Naija's playful, exploratory personality. This song sums up that aspect perfectly: bright and sunny and adventurous.
