Retain copies of all music with a registered ISBN at the Library of Congress. Allow musicians to buy copies for the cost of the media. In order to qualify as a musician, the person must perform at least one unit of time of live music, or produce one recording of original composition, per time period. In this way the copyright laws can still be wielded against cheating consumers, while not stifling the need of musicians to explore and absorb a vast array of works in order to produce significant new art. It also provides an incentive for people to compete for performance venues by improving their music, in that way promoting the progress of the useful arts.
