How is music and movies are protected by the copyright law?

Answer 1

It allows anyone who publicly performs, copies or makes adaptations to be sued if they do not obtain a license.

There are actually two US c ompanies whose sole business is to track the use of protected material by unauthorized users and collect the royalties.

Answer 2

Yes. Both the song itself and the performance of it are protected separately, so for example sheet music can be controlled by one company, and a recording of the same song by another.

Answer 3

To enable the songwriter and/or artist to ascribe value to their intellectual property, and possibly derive an income from it, so they can stop waiting tables.
