Yea i thought the music was one of the best parts of the trailer. It was really great.

I always felt the electric guitars and some of the really synth tracks didn't fit the battles in XIV. It may if I was fighting Garleans or something, but lets be honest here, all of us have spent 99% of the time in XIV fighting crabs/squirrels/raptors/beastmen. And they are NOT technological enemies that would have kinda fit the battle themes originally designed.
