Sony Music Files a Second Udio Lawsuit Over 30,117 Recordings a Judge Barred From the First

The Verge·medium signal

Sony Music filed a new copyright suit against AI music generator Udio on July 20 asserting 30,117 sound recordings — from Elvis Presley's 'Hound Dog' forward — that a judge refused on June 29 to let Sony add to its existing case. Sony identified the works via audio fingerprinting during discovery of Udio's training data, which it says surfaced hundreds of thousands of its recordings. Sony cites the court's own language that plaintiffs may pursue all infringed works but 'there is no requirement that it be done in [that] lawsuit' as the basis for splitting the claims.
