Wow, what an explanation! Thanks a lot for this :). I'm gonna take some time to read it for a second and third time to really grasp the points you make, but I am already happy that I understand most if not all that you say. Music theory for the win! Oh, and all the songs that I've heard so far which uses the 'challenge of reduction' use the same interpretation as you, so don't worry! It's me who interpreted it wrong ;). Thanks again :D
