A group of music publishers led by Concord Music Group and Universal Music Group are suing Anthropic, according to a report by Reuters . The suit accuses the AI company of illegally downloading more than 20,000 copyrighted songs, including sheet music, lyrics and compositions. The publishers issued a statement saying that the damages could amount to more than $3 billion. The suit was filed by the same legal team as last year's Bartz v. Anthropic case . The music publishers say they found that Anthropic had been illegally downloading thousands of songs during the discovery process of that suit .
