have you considered a schedule of a length in between one week and two weeks? like maybe ten days, since you said that's how long you can reasonably expect to make a song-video
the 7 day week is so famous and so widely used, any schedule that is synchronized with that seems to automatically have quite a bit of power and credibility that would be severely lacking otherwise. in my current circumstance, i actually do wish very much that the worldwide business week was 10 days
