When Kelly talks about freeness, he refers to it as being the second phase of a three stages copydom in the context of the music industry. The first phase included the perfection in duplicatng the music to make it widely available. Audio cassettes and compact discs contain duplications of an artist's music. Napster, as well as any other file sharing software, has brought the idea of freeness into the spectrum. Analog copies of music have been transformed to digital copies, which are perfect copies, fluid, and especially free. You get the same music as your friend, but you didn't have to fork out any cash. Kelly predicts that music's liquidity will prevail in the third and final stage of the music evolution. "Copies are so ubiquitous, so cheap (free, in fact) that the only things truly valuable are those which cannot be copied." In other words, people will tire of having clones and turn to having music authenticated and personalized, but this won't come without a price (and people will pay).
