"Master Rights" refer to the ownership and control of the original recording of a song or piece of music. This includes the right to reproduce, distribute, and license the recording for various uses, such as in films, commercials, or streaming services. The holder of the master rights can earn revenue from these activities. Typically, the artist or record label that produced the music holds the master rights. However, these rights can be sold or transferred, allowing other parties to manage the recordings. Understanding master rights is crucial for artists and producers in the music industry.
