This is the best summary I could come up with:

A trio of major music publishers are stepping into the legal battle against generative artificial intelligence to stop the use of their copyrighted material to train AI systems, this time in a lawsuit against Anthropic.

Universal Music Group, Concord Music Group and ABKCO sued the company in Tennessee federal court Wednesday, accusing it of “systematic and widespread infringement” by copying and distributing lyrics from at least 500 songs from artists such as Katy Perry, the Rolling Stones and Beyoncé.

When asked the lyrics to Katy Perry’s “Roar,” which is owned by Concord, it provided an near-identical copy of the words in the piece.

The publishers argue there’s already an existing market that’s being undercut by Anthropic, which is backed by Amazon, pilfering their material without consent or payment, citing music lyric aggregators and websites that have licensed their works.

The argument is meant to undermine Anthropic’s anticipated fair use defense, which was effectively reined in when the Supreme Court issued its recent decision in Andy Warhol Foundation for the Visual Arts v. Goldsmith.

In that case, the majority emphasized that an analysis of whether an allegedly infringing work was sufficiently transformed must be balanced against the “commercial nature of the use.” The music publishers are attempting to establish that Anthropic’s alleged copyright infringement hurt their prospects to profit off of the material by interfering with potential licensing deals for use of their lyrics.
