I'm into anime as well but that is clearly two songs that they decided just to hastily slap together and call a primal theme.

Like many others think, the first half is great... The second...ehhh, not so much. Good on its own but not combined.

SE needs to do its homework more and figure out what people would like more in terms of primal music rather than just cater to one side of its fanbase. I.e. The Japanophiles.
