What about drug companies. In just a few years Viagra is entering the public domain and that's more valuable (and cost more to create) than every single song produced in 1961 and 2010. The reality is Artists get a ridiculously long period of time to extract value from their work and we would probably be better off if copywrite lasted 20 years than what it's been extended to for the same reasons that patents are so short.
