A music supervisor is the person in charge of placing music in films, TV shows, advertising and video games. Clients approach music supervisors with an idea of what kind of music they need for their project (or sometimes even specific ideas of songs they want), and the music supervisor then finds the appropriate music and acts as a liaison between clients and the rights holders of the music. They work to arrange the appropriate licensing for the songs, and work to negotiate licensing deals that come in on budget for their clients.
