The file 107.wav in this game is something for choir and orchestra.
I'm pretty sure the choir sings "Requiem Aeternam" so it's possibly a Requiem Mass.
In the credits Agnes quotes:
"Greig" is obviously a typo for Edvard Grieg and the file 105.wav is for sure The Morning Mood from the Peer Gynt by Grieg, but I don't think Grieg wrote also a Requiem.Music by Eternal Mana, Greig, HIM, Eminem, Bruce Springsteen, Guns and Roses.
So, does anybody knows what music is the file 107.wav?
