Area and coordinates: [Final Endwalker Zone]

Steps:
1. After a specific Endwalker main story quest, the BGM music that changed to support that specific story event does not cease and overrides the final zone original music.
2. The lyrical variant of the original BGM (from story point above) plays on repeat, constantly repeating the song ad infinitum with no way to change the music outside of turning BGM off
3. Reinstalling the client does not resolve this bug
