Sony Music is moving to add more than 30,000 recordings to its copyright lawsuit against AI music generator Udio, alleging the works were ingested to train its models. For marketers using AI-generated media, provenance is becoming a live question.
The AI tools that generate media are being built faster than the law can decide what they were allowed to learn from.
Sony Music wants to widen its fight with AI music generator Udio. The label is moving to add more than 30,000 recordings to its copyright case, alleging Udio copied and ingested 30,442 works to train its models. The list runs from Elvis to the present.
The case has legs the others lost. Universal and Warner both sued Udio in 2024 and both settled, in October and November. Sony did not. Its claim survived Udio's attempt to have it thrown out, partly because Sony alleges Udio got around YouTube's anti-stream-ripping tools to build its training library, which Udio has admitted scraping. Udio's defence is fair use, the argument that training on unlicensed work is transformative enough to be legal.
That question is still open, and Sony expanding its claim says the labels think they can win it.
Why it matters
Most marketers will never touch Udio. Plenty are already using AI to generate music, voice, images and video for social and ads. The Sony case is a reminder that the material under these tools is contested, and the people who made the original work are coming for it.
This is the same reckoning playing out across AI. First books, now music, and the pattern is consistent. The output feels free and instant. The provenance of what it was built on is turning into a legal bill someone has to pay. If you build a campaign on AI-generated media, you are trusting a supply chain that is being fought over in court.

What to do about it
Know how your AI media tools were trained. Providers vary on data sourcing and what they promise business users. Ask before you rely on them.
Check for indemnity. Some tools cover you if an output triggers a claim. Know whether yours does before you put AI-made media into a paid campaign.
Keep licensed alternatives for anything high-stakes. For a brand campaign with real spend behind it, properly licensed music and stock is a cheap insurance policy.
Review outputs that echo a real work too closely. A generated track that sounds like a specific song is a risk a human ear can catch. Do not ship blind.
Watch how these cases land. The settlements and the fair-use rulings will set what AI media tools can legally do. It is worth following, not ignoring.
The tools are useful and they are not going away. The question of what they were built on is being answered right now, in court, and the safest position is to know your supply chain before someone else audits it for you.
