The Recording Industry Association of America announced two copyright suits brought by Universal Music, Sony Music, and Warner Records — against Suno in the District of Massachusetts and against Udio in the Southern District of New York — alleging that both had copied sound recordings on a mass scale, without licences, to train their models. "These are straightforward cases of copyright infringement involving unlicensed copying of sound recordings on a massive scale," said RIAA chief legal officer Ken Doroshow. What had happened in images was now happening in music, with the difference that the rights holders moved together through their trade body. Suno and Udio were the best-known services for generating music.
