Sony Music has sent letters to over 700 tech firms, including Google, Microsoft and OpenAI, demanding to know if they have used its songs to develop AI systems.
In the letter, Sony stated that it has "reason to believe" that the addressees "may already have made unauthorised uses" of its music. They have asked for the details of songs they have trained AI systems on, and how those songs were accessed, as well as the number of copies of those songs, whether they still exist and how long they existed for.
