Find XO: Sony's attempt to add 30,000 tracks was blocked, but the real weapon aimed at Udio is different (news.bloomberglaw.com)

- Sony Music tried to add 30,442 tracks to its copyright lawsuit against Udio but was denied by the Southern District Court of New York, so the lawsuit remains limited to 333 tracks. - Universal and Warner settled the lawsuit through licensing agreements, leaving only Sony remaining. - The real issue is not the number of tracks but the allegation of DMCA circumvention aimed at YouTube stream ripping. - When dealing with generative music, where and how the data was obtained could trip up the case even before fair use debates.
