Now you need to define what a unique, profound emotion is.

And you need to define great execution.

And you need to explain why intentionally having poor execution couldn't express a unique, profound emotion. On Radiohead's biggest hit Creep "That's the sound of Jonny trying to fuck the song up. He really didn't like it the first time we played it, so he tried spoiling it. And it made the song."

At the end of the day it's always going to seem all subjective and a matter of opinion. Because it's too hard to pinpoint the objective part of what we are doing when we decide what's great and what's garbage. If there even is an objective part.
