HOW DO YOU DO IT? What's your secret man?
This starts out like one of those samurai-themes. Do they typically use pentatonic scales, is that why it works out so well? Or is it just the good old Selkione magic making it work?
And of course you manage to turn it into a heart-racing beat-dropping banger xD. It is great, starting soft and simple (yet awesome), and slowly getting higher-paced and complicated (yet awesome).
But damn, 0:43 - 0:60... I am convinced it is just 4/4 but it sounds so wacky to me because of that off-beat stuff going on. Yet (obviously, why not) you manage to make even that confusion sound good.
What more is there to say? Oh, I know! "it's too short (as it often is)."
Nice song ;)
