A radio signal can become a business use
Buying a radio does not necessarily cover every way its music is heard. Copyright law treats playing a song for customers in a restaurant as a public performance: the music is being shared in a place open to the public, rather than listened to privately at home. In the United States, some smaller businesses and certain ways of playing music may qualify for exemptions, so whether a diner needs a license depends on the circumstances.
One song, several rights
A recorded song involves rights in both the underlying composition—the music and lyrics—and the particular recording. Rights organizations, often called performing-rights organizations, license public performances of compositions on behalf of songwriters and music publishers. Their licenses commonly let a business play a broad catalog without negotiating separately for each song.
The radio station has its own permission to broadcast music, but that does not automatically settle the diner’s separate use: the station sends the program out, while the restaurant makes it audible to customers in a public setting. The exact licensing arrangements and legal requirements can vary, which is why a radio playing in a business can still raise a licensing question.
The fee turns scattered listening into royalties
For a diner, a license fee is a cost of offering music as part of the customer experience. For creators, collecting individually from every restaurant every time a song plays would be impractical. Licensing organizations pool those permissions and distribute collected royalties to the rights holders they represent. The system lets a small business use music without tracking each performance itself, while directing some of the cost back toward the people who made the songs.
