Venus Limperatrice LLC is responsible for ensuring the songwriters and composers receive payment when their compositions are used commercially. There are several types of royalty: mechanical royalties derive from the sale of recorded music, such as CDs or digital downloads. These royalties are paid to publishers by record companies. Performance royalties are collected by performance rights organizations such as SESAC, BMI, ASCAP or PRS and are paid by radio stations and others who broadcast recorded music; and are paid by venues, event organizers for live performances of the compositions. Synchronization royalties are required when a composition is used in a film or television soundtrack. These royalties typically pass through the hands of a music publisher before they reach the composer.
