I really like Primal Judgment http://www.youtube.com/watch?v=136shMdKe7c
I wonder if originally they were going to use that for all the primals.

Also I have loved the Castrum nova battlefield music ever since the alpha music was put out there

Oh and Halls of Flames is pretty awesome too. I loved being in Ul'Dah so much more when it played through the whole city. Actually I like all the GC hall songs, and a ton of others heh. I listen to the songs more out of the game than in I think... Also, I think it fitting in this thread to show appreciation for AMagicalKarp. He gets us the new tracks fast
