Good post, but I'm just not seeing why the emotion in question should in any way require a factual statement that something is (unattainably) perfect. Maybe this is just a basic philosophical difference? Certainly when I listen to some of these songs (highly recommended, BTW), I'm pretty sure it's with the same emotion (including the same neural circuits) with which a devout Christian listens to hymns, without any requirement that perfection come into it.
