If you have verse melodies and rhythms as good as this, you are in rarefied air. If you have a chorus that is as complex a sequence as this and still catchy, you are in super-rarefied air. If it turns out that this wasn't the chorus but just a transition with a masterful build to the real chorus - and the real chorus is the payoff of "Come Undone," welcome to Cloudcuckooland.
