Yodragon | Ansurek's Defeat - Cutscene Music of WoW: The War Within @YodragonWasTaken | Uploaded September 2024 | Updated October 2024, 14 hours ago.
This is the music that plays during the final cutscene of the Nerub-ar Palace raid, after Queen Ansurek is defeated.

I like how prevalent Xal'atath's theme is in her cutscenes.

Also, looks like this is going to be the last cutscene track we'll get until the next major update.
Maybe it'll be like Dragonflight, and we'll get some more in the 0.5 patches? Hopefully they'll have unique music too...
