Three organizers from other communities have asked how the feedback format works, so here it is written down.
The rule is that the room says what it heard before it says what it would change. In practice that means the first four or five responses to a track are descriptions: the drums felt like they were behind the guitar, the second verse felt shorter than the first, the vocal disappeared under the chorus.
Descriptions are almost always more useful than suggestions, because the person who made the thing already knows their options. What they cannot know is what it sounds like from outside their own head.
