The Brazilian Society for the Administration and Protection of Intellectual Rights, or SOCINPRO, administers and protects artistic works of musicians, performers, composers, authors and producers in Brazil. SOCINPRO is one of the six member companies that form and manage ECAD, BrazilŐs Central Office for Collection and Distribution) of copyrights. Together with the National Congress, SOCINPRO advocates for its members to update intellectual property legislation and combat piracy.
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.
