BIEM is an international organisation representing mechanical rights societies. These societies operate in most countries and license the reproduction of musical works, including musical, literary and dramatic works. Their members are composers, authors and publishers, and their clients are record companies and other recorded music users. Mechanical rights societies also license the mechanical aspects of downloading music online. Producers need a licence from the owners of the works to produce a CD, audio cassette or LP containing protected musical works, and they pay royalties for each copy produced and sold.
