The Georgian Copyright Association, or GCA, is a non-profit, non commercial, legal union, created to implement and protect the rights of its member authors and performers, or their successors. It is the only collective management organization within the Republic of Georgia. At the Georgian territory, the Association represents and protects the rights of more than 3 million authors registered in more than 150 countries and territories throughout the world.
Music Publishing is the business of protecting and promoting song copyrights and collecting the royalties that these copyrights generate. Think of a song as intellectual property (it's an original piece of art!), and music publishing as the business that makes sure that songwriters get paid a fair compensation when their intellectual property is used by companies. Those companies could be record labels (mechanical royalties), radio stations, bars, and restaurants (performance royalties), or film studios and advertising agencies (sync license fees), and many more.
