DAOR-SIGNAL-20260830-001 — Sony and Warner Chappell sue Anthropic over alleged mass copying

Sony Music Publishing, Warner Chappell Music and affiliated publishers filed a complaint against Anthropic in the US District Court for the Northern District of California on August 28.

Anthropic co-founders Dario Amodei and Benjamin Mann are also named as defendants.

The publishers allege that the defendants obtained copyrighted material through torrenting, scraping and bulk downloading, then copied musical compositions while developing and operating Claude models. The complaint reportedly identifies tens of thousands of compositions and includes allegations involving lyrics and sheet music obtained through pirate book repositories and licensed lyrics services.

The publishers also allege that copyright-management information was removed and that Claude can reproduce protected lyrics. The claims include direct infringement, contributory infringement and removal or alteration of copyright-management information.

The plaintiffs seek a jury trial, destruction of allegedly infringing copies, information about Claude's training data and statutory damages.

These are allegations. The filing does not establish that Anthropic or its founders are liable. Anthropic had not provided a substantive public response when the initial reports were published.

DAOR-SIGNAL-20260830-002 — UK performers organize around statutory control of voice replicas

Recovery lane: The campaign was reported August 28 at 05:00 UTC and was approved from the August 29 scan.

Approximately 80 performers have backed the Save Our Voices Now campaign calling for stronger UK protection against unauthorized AI voice cloning.

The campaign sent an open letter to the UK government and launched a public petition seeking statutory legal ownership of an individual's voice. Supporters work across acting, voice performance and music; singer Sandi Thom is among the reported signatories.

The proposal concerns AI-generated replicas that imitate an identifiable person's voice without authorization. Campaign supporters want individuals to have a direct right to control such uses instead of depending exclusively on existing copyright, contractual, privacy, data-protection or passing-off remedies.

The campaign does not create new law. The UK government had already announced its intention to consult on digital replicas before this campaign, and that earlier commitment should not be represented as a government response caused by the open letter.

Why it matters

The Anthropic complaint separates several issues that are often collapsed into a single training question: how material was acquired, whether the copies were authorized, whether copyright-management information was preserved, how works entered model development and whether protected expression appears in outputs.

The UK campaign exposes a different boundary. Authority over a composition or sound recording does not necessarily establish authority to reproduce the identity embodied in a performer's voice. A synthetic vocal can imitate a person without copying a substantial part of an existing master.

Together, the developments reinforce the need for both training-data provenance and identity-specific consent records.

DAOrecords analysis

DAOrecords should preserve separately:

• training source, supplier, acquisition method and acquisition date;
• whether access was licensed, public, restricted or allegedly unauthorized;
• copyright and attribution information present at acquisition;
• any alleged removal or alteration of that information;
• models and versions that received the material;
• output-level reproduction or similarity evidence;
• the represented individual in a synthetic performance;
• whether a voice was cloned, generated, transformed or naturally performed;
• identity authorization, permitted services, uses, territories and commercial terms;
• revocation, termination and evidentiary status;
• allegations, party responses and judicial findings as distinct states.

A complaint must not be recorded as proof that infringement occurred or that a specific work entered a model. Likewise, the UK campaign must not be represented as an enacted statutory right.
