I often listen to my stuff too much till I'm just tired of hearing it and I lose all bairing on what I want to do with it. I find I have to put it down for at least half a day and then when I go back to it I have to try to be in the moment as best I can. Usually when I come back to it like that it starts to become clear what needs to be done pretty quickly.
Idk if anybody else has this problem but I can become invested in how a track is, and find it hard to change parts that should be changed. To move past that I just save a new version and then feel I can hack away at it without fear of losing what it was.
Idk, the way you described your cycling thoughts on the task I thought maybe that would be relevant.
