O Fortuna - Carmina Burana - Epic indignation

This is such a cool piece of music! I looked at a number of videos on YouTube and there are some really interesting ones. There's a Star Wars one and horror ones, Andre Rieu, and lots of choirs. I like this one because you have the words to sing along with and a translation, and the video is good. Knights are good. I imagine some kind of violent religious rite, a passionate sacrifice, when I hear this, so it works for me.
Heavy metal lovers should like this. O Fortuna has the same elements of anger, indignation, and violence that a lot of metal pulses with.
