Music licensing is a crucial subcategory within the music industry that involves the legal permission to use copyrighted musical works. It ensures copyright owners are compensated when their music is used in various contexts including films, TV shows, commercials, video games, streaming platforms, and public performances. This sector encompasses multiple license types such as synchronization, mechanical, performance, and master recording licenses, creating revenue streams for artists, publishers, and rights holders while enabling legal music usage across media and commercial applications.
