*MUST BE USED WITH FANTASTIC CHORUS*
Der Hölle Rache from Mozart's opera Die Zauberflöte.
When the song skill came out this is the first thing I wrote to test it myself.
If any song in the world could challenge a synthetic game voice this is the one.
I would say Mabi still can not do very well with this song. I had to lower the vocal octave while writing because Mabi voices do not go as high. I also cut the ending short due to Mabi limits and added a higher note for a replacement.
