In a world where copyright only lasts 10 years, what happens to the musician whose song from 20 years ago is used in a movie and becomes super popular? Do they get royalties or are there no royalties involved?
I want a system that doesn't syphon money to the corporations over the individual creator and the corporations can't tell me I can't use the song.
No royalties, as the 20-year-old song would be in the public domain, so no one can tell anyone they can't use the song. The vast majority of songs that make a profit will do so within the first few years, with almost or actually nothing after 10 years. The copyright system should optimise for public benefit and the vast majority of works, rather than the tiny number of big successes.
