I intend to share it with every fan whenever a video of it shows up, for from my first watch of that movie I wanted to know the damn lyrics. So after repeating videos of the sort many, many times, I came up with this. I tried myself to keep some "consistency" with the words used, like establishing the language itself, but only how I hear it. My second try on trying to put lyrics on that incredible scene. It sounded a lot like the Uruk-Hai warcries and how the orcs and uruks from Sauron besieging Minas Tirith. *This part between [ ] is to be picky with, for I tried my best to decipher what's behind the crescendo.
I recommend you look at the vid "Harkonnen chanting" from Eagles to Mordor. I left a lengthy comment there breaking down all the sounds, from 0:00-1:25 in this vid I believe. Maybe it can help your personal translation play.
