I have found another song but when i go around i can only see a very short version of the song. im wondering if you already have the piece in your archive, if not then im hoping im not asking too much. its almost 8 minutes long.

By the game Parasite Eve
Artist-Yoko Shimomura
Song-Main Theme Orchestral Version
Album- Parasite Eve OST

Theres one more song too, its very short and its called Phrase of Aya, same album, same artist.
