Production music library is the name given to recorded music that can be licensed to customers for use in film, television, radio and other media. Oftentimes, the music is produced and owned by production music libraries.
Production music has traditionally been distributed on vinyl or CD but it is now also available via download. A production music company is basically a publishing company, or a department of a publishing company, that specialises in marketing, licensing and collecting royalties for production music. The end user is usually a film, TV or radio production company — but tracks can also be used for computer games, web sites, live events and even ringtones. Users choose tracks they want to include in a programme and can license them very quickly, through licensing agencies worldwide, at a set licence fee per 30 seconds of music. Very often this is cheaper, quicker and less complicated than commissioning a composer.
