DRULES AI
Sony Music and Universal Music Group filed a new copyright infringement lawsuit against Suno in Boston federal court, targeting the company's freshly launched v6 model family. The complaint alleges v6 is "the fruit of the same poisoned tree," built on technical insights and data patterns derived from earlier versions trained on unlicensed material from their catalogs.
⚖️ Core Allegations Exposed
The labels cite over 60,000 songs in their escalated claim, arguing that retiring old models and retraining on Warner, BMG, and Believe licensed tracks doesn't erase the foundational infringement. Court filings reference Suno's own admissions about using user data alongside licensed catalogs, claiming the new system still generates outputs too similar to UMG and Sony artists. This follows a prior suit and comes weeks after Suno touted v6 as a clean break with faster generation, better prompt adherence, and new features like targeted section editing.
Legal experts following the case note the "poisoned tree" doctrine could prove pivotal. If courts accept that iterative improvements carry forward infringing knowledge, every future AI music model may face scrutiny regardless of new licensing deals. Suno has struck partnerships with Warner Music Group — which exited the original litigation — plus BMG and Believe, positioning v6 as industry-aligned. Warner executives have publicly framed it as opening revenue for artists via opt-in remixing tools.
📈 Industry Split Widens
The lawsuit highlights fractured alliances. Warner's deal includes future artist opt-in features, while Udio has settled with Universal and signed Warner but still faces Sony heat. Meanwhile, collecting societies are piling on: SOCAN's recent filing spotlights an unauthorized K-pop version of Avril Lavigne's "Sk8er Boi" allegedly generated by Suno, adding international pressure. Suno counters that v6 was built from the ground up, retiring all prior models entirely.
Engagement on X surged yesterday with creators debating commercial risks. Paid subscribers — now over 2 million — worry about monetizing outputs if injunctions hit. Platform usage exceeds 100 million users, with annual recurring revenue topping $300 million, yet the legal cloud threatens enterprise adoption.
🔬 What Creators Should Watch
Professional users have adapted workflows around v6's strengths: tighter genre control, coherent long-form tracks, and the new ability to regenerate single sections via prompt without restarting entire songs. However, the suit may accelerate watermarking mandates seen after the GEMA loss in Munich. Independent artists using Suno for stems or demos face unclear rights if tracks blow up virally.
Broader implications extend to competitors like Udio, Google Lyria, and emerging tools from ElevenLabs. Labels licensing to some AI firms while suing others creates a patchwork that favors deep-pocketed platforms capable of parallel legal and licensing tracks.
Bottom line: Suno's v6 pivot to licensed data failed to shield it from majors' claims, signaling that AI music's legal future hinges on proving models can fully unlearn infringing patterns.
