most of the times i finish a track during one day, and only come back if i find something really annoying.
i have to magic tricks....
1. let your track play, and go to the toilet, and sit down and listen !!!
you can learn a lot about your balance from far away....
2. when everything is mostly ready , try listen as silent as possible.... turn down the volume of your speaker...
the elements that really stick out, are most of the times to loud.
