Sony Music is sending warning letters to more than 700 artificial intelligence developers and music streaming services globally in the latest salvo in the music industry’s battle against tech groups ripping off artists. The Sony Music letter, which has been seen by the Financial Times, expressly prohibits AI developers from using its music — which includes artists such as Harry Styles, Adele and Beyoncé — and opts out of any text and data mining of any of its content for any purposes such as training, developing or commercialising any AI system. Sony Music is sending the letter to companies developing AI systems including OpenAI, Microsoft, Google, Suno and Udio, according to those close to the group. The world’s second-largest music group is also sending separate letters to streaming platforms, including Spotify and Apple, asking them to adopt “best practice” measures to protect artists and songwriters and their music from scraping, mining and training by AI developers without consent or compensation. It has asked them to update their terms of service, making it clear that mining and training on its content is not permitted. Sony Music declined to comment further. The letter, which is being sent to tech companies around the world this week, marks an escalation of the music group’s attempts to stop the melodies, lyrics and images from copyrighted songs and artists being used by tech companies to produce new versions or to train systems to create their own music. The letter says that Sony Music and its artists “recognise the significant potential and advancement of artificial intelligence” but adds that “unauthorised use . . . in the training, development or commercialisation of AI systems deprives [Sony] of control over and appropriate compensation”. It says: “This letter serves to put you on notice directly, and reiterate, that [Sony’s labels] expressly prohibit any use of [their] content.”
