An idea from a friend of mine.
Personnally, I wholehearted recommend you to have a try. These BGMs are really impressive.

Require SuperBLT and Beardlib

Stealth Part: ReSound Wave - The flow of time
Loud Part:* Ishigami Shizuka - Kurenai Fubuki* (石上静香 - 紅吹雪)

2 BGMs from Toki o Tsumugu Yakusoku / 時を紡ぐ約束

How to Install: Put Kurenai Fubuki folder into mod_override folder. Simple.

Enjoy.
