DANG! I love this! The koto is very professional-sounding, and I'm interested to know what the plugin used was. It's also a very very well-mixed song in general. Lyrics please!!
The one major suggestion I have is that you should really put the following warning on this song:
WARNING: DO NOT TURN THE SONG UP SO THE KOTO IS LOUD. THE DROP *WILL* BLOW YOUR SPEAKER. AND ALSO PROBABLY YOUR EARDRUMS.
