Intellectual and artistic property are really unique in the eyes of the law... and in the eyes of the creators. Look at Taylor Swift, for instance; she signed some bad agreements and inadvertently gave away rights to her own work to someone else. Now to profit from her own artistic vision/performance she is re-recording in order to legally use her own artistic creations.
It's interesting that the copyright law is one of our oldest laws: "United States
copyright law traces its lineage back to the British
Statute of Anne, which influenced the first U.S. federal copyright law, the
Copyright Act of 1790."
