There really is a lot of power behind this melody. This one sounds especially Tron/Daft Punk influenced. Could totally see it for a level in a game, it'd fit really well. Something with a sort of "evil cathedral castle of darkness" type atmosphere to it. I just love the melody, but as well, the instrumentation here is great too. And of course, the loop is splendiferous. Loops/transitions/endings are what I always listen to the most it seems.
