When you stream a song, a complex set of copyright transactions happens in the background. Music copyright has two distinct layers: the composition copyright (melody and lyrics, owned by the songwriter, managed by performing rights organizations like ASCAP or BMI) and the sound recording copyright (master rights, typically owned by the record label). A single stream generates royalties owed to both. Reference: JASRAC: streaming royalty distribution.
The Blurred Lines Case
In 2015, a California jury found Robin Thicke and Pharrell Williams liable for copyright infringement of Marvin Gaye’s “Got to Give It Up.” The similarity was in the groove and feel rather than specific melodic content — controversially expanding the scope of musical copyright.
AI and the Next Frontier
The most contested current question: when a model trains on existing recordings, does it infringe copyright? When AI generates a song that sounds like a specific artist, is there a claim? Courts and legislators are working through these questions without settled answers. Reference: US Copyright Office.
