problem_evidence: Sony has filed a second lawsuit against AI music generator Udio over 30,117 recordings
quick_read: On 2026-07-21, Sony filed a second lawsuit against AI music generator Udio, alleging infringement of 30,117 recordings. The complaint reportedly leverages licensing deals obtained by rival AI music companies to argue against Udio's fair-use defence.

The case matters because it tests whether AI music models can claim fair use when competitors have chosen to license catalogs, potentially shaping how music rights are cleared for generative models. What remains uncertain from this source is the court venue, the specific recordings at issue, and whether damages will be awarded.
limitation: 
tag: Evidence-backed problem

How to verify without trusting this page

Fetch the canonical text of any version from /api/record/TRV-2026-0504 and hash it yourself — for example shasum -a 256 on the saved canonical field. The result must equal content_hash, and each version’s text ends with prev:followed by the prior version’s hash (version 1 chains to 64 zeros). If a single character of any version had been altered since certification, the chain would not reproduce.
