For those interested, the theme’s name seems to call to:

Orpheus, the Greek figure who went to the underworld to reclaim his wife. In this case, Ningirsu trying to bring back his sister Ib from the dead after she seemingly killed herself to stop Lee from using her body with the Knightmares.

Orgel/Orgol, a Music Box (also the term for Organ)

Belphegor, the Demon Lord of Sloth who is connected with bringing laziness and the corruption of men through technology. And in the World Legacy setting, things that refer to music are basically always Bad Things (TM).
