The project works in terms of quantity! Not so much with quality - but the idea is to at least have the discipline to keep at it. I know what you mean with time/kids etc - I rarely do more than a couple of takes of each track, and often just one. I've had months when I had to to a song from scratch on the last day. The idea is that they are rough demos that will eventually be played by more talented musicians than me. I think if I worried about getting them "right" I'd never get anything completed!!
