I have noticed a direct inverse correlation between the happiness of musicians and the greatness of their music. As my rock idols enter out of dangerous relationships and into successful marriages (Ben Harper) and out of drug-induced bondage into clean and sober living (Jeff Tweedy of Wilco), their music suffers. The angst is gone. Where music used to serve as an outlet, a necessity to work out inner-turmoil, instead, they are just out enjoying life. And we all have to suffer because of it.
