There are several types of income interests generated by the use of copyrighted music. They include:

They’re earned when a composition is performed publicly or broadcasted, including on radio, TV, live performances, and certain streaming platforms.

• 3. Synchronization: These fees are earned when a composition is synchronized with visual media, such as movies, TV shows, commercials, and video games. The rights holders receive payment for the use of their music in these visual productions.
