Interesting... very different song choice!
Maybe you should explain the title at least
.
Anyway, as for the map itself: Timing is perfect, and the patterns are mostly very original and well layed out. The only major issue I have is the long break period in the middle of the song. I can see some people getting really bored during that, since there is nothing to really do for >30s (although I did start overanalysing that background picture).
Let's see what others have to say about this.
