Critiquing and assessing what you have, feedback from others.
Have you ever done too much of something that you just had to get away?
You can take a break from all the listening, then come back to it with fresh ears and a fresh perspective. You can also involve others to help assess all that’s been done so far. Your album’s producer can give key points. You can recheck the feel, flow and sound of your songs. Try to play samples on different players – in your car, in your mp3 player, etc. See what comments come up and what you can possibly do to make changes for the better.
