The Musical Copyright Society Nigeria (MCSN) is an incorporated collective association of authors, composers, arrangers and publishers of music.
Before Nigeria gained independence from Britain, most Nigerian composers and authors were registered with the Performing Rights Society (PRS) and the Mechanical Copyright Protection Society (MCPS), both of the United Kingdom, who were responsible for collection and distribution of performing and mechanical rights in musical works.
In 1984, MSCN was set up to take over the responsibilities of both the PRS and MCPS in Nigeria. While many Nigerian creators transferred to MCSN, others remained with PRS and MCPS. MCSN entered into reciprocal representation contracts with both PRS and MCPS by which MCSN became vested with the copyright in virtually the entire repertoire of copyright music available in Nigeria.
