Copyright law is just broken and the only ones who are benefiting a the music and movie studios. I never understood why copyright should even extend beyond a persons death. Everyone else in 'normal' jobs gets paid for their work until they leave, retire or die. If a plumber, accountant, IT support worker etc died tomorrow would you expect to carry on paying for work they had already done for another 80 years?
If you want your family to be financially secure after your death get life insurance or leave them money in your will why should creative artists have special laws that only apply to them?
