ROM Hack Tomodachi Life unused song restoration

[LeafyIsHere]

You may know that the original Japanese release of Tomodachi Life (Collection) had an "Enka" song that could be performed in concert hall.
It looks like this song is still in the game's files, even including roughly translated lyrics:

I am working on re-enabling this song in the game, let me know if you guys even care about this!
