@Dudebro @snacks @jeffcliff Imaginary property does not exist - using that term gives even more credibility to a confusion.

Copyright laws can only hand public rights to private interests - it can't every go back according to the USA congress.

Yes, the copyright term length is ridiculous - music is not a special case - the ludicrously long term length apply to almost all works.

Many patents have been granted, with restrictions very much like a patent saying that only Rhianna could sing in a flat major - but at least those expire after 20 years (too bad patent offices just proceed to grant another invalid patent).
