The Eastern Caribbean Collective Organisation for Music Rights (ECCO) Inc. is a society of writers & publishers of music in which royalty payments to its members and members of affiliates totaling over $330,000. Through reciprocal agreements with societies, ECCO represents and can license virtually the whole worldwide repertoire of copyright music for public performance, broadcast, cable transmission, online and mobile use.
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.
