This is interesting. Some parts have a very NES Nobuo Uematsu sound while others have a very Takashi Tateishi sound. And still others have a Robert Fripp type sound (around the 1:33 it starts).
I like hearing so much variation in a song, especially in a loop which potentially goes on forever. It keeps the listener interested.
The one complaint I have is the way this song loops. It almost sounds like ends before starting over. If the end of the loop were more seamlessly connected to the beginning of the song, this song would be almost perfect!
