Ok, so since it is all "subjective" then you have to concede that a song which is just 1 hour of a single note being played is equally good. Or maybe, instead of devolving into absurdity we can just say that there are come qualities of being better or worse that most people can agree on. Of course, you can simply bite the bullet and say "yep. The song with 1 note in it is subjectively just as good".
