Don't get me wrong here, I pretty much love every BGM in this game. But I noticed that almost no primal have a theme without lyric, Ifrit and Bismarck and Zurvan being the only ones. And I really loved Bismarck's fight, starting phase 2, "Woe that is madness" really render well there, and I really love that there was no need of lyrics to make it feels powerful, just like "Infinity" for Zurvan. I wish we could have more primal theme in the future without lyric to be able to enjoy the music only.
