Is AI Music Copyrighted? Who Owns an AI-Generated Song

"Is AI music copyrighted?" gets confusing answers because it's three questions wearing one coat, and the answers genuinely differ:

1. Do I own this track — can I release and sell it? Usually yes. This comes from your tool's terms of service, not from copyright law.
2. Can I register a copyright on it? Often no, at least not for the purely AI-generated parts. This comes from copyright law, and it's about human authorship.
3. Will it get flagged as someone else's? Usually no, but it can happen.

Most arguments about this topic are two people answering different questions. Here's each one separately.

Question 1: Do you own it?

This is settled by contract, not copyright. Whatever rights you have to a generated track come from the terms of service of the tool that made it.

Terms vary a lot, and the differences that matter are:

• Commercial use. Can you sell it, monetize it, use it in a client project? Free tiers frequently say no — output is for personal or evaluation use only.
• Exclusivity. Some services grant you a licence to use the output but reserve the right to license similar or identical output to others. That's very different from owning it.
• Attribution. Some require crediting the tool.
• What happens when you cancel. A few services tie your rights to an active subscription, meaning tracks you released while subscribed become a problem after you leave. This one is buried in the terms often enough to be worth searching for specifically.

Before you release anything, find the answer to those four for your plan — not the service in general, the plan. The gap between a free and paid tier is usually exactly here.

With Rewave, you own what you generate and can release it commercially without attribution — on the Pro plan and above. Our own Starter tier is MP3-only and excludes the commercial licence, which is precisely the per-plan trap described above; we are not exempt from it.

Question 2: Can you register a copyright?

Here the answer turns on human authorship, and this is where the genuine legal limitation sits.

In the United States, the Copyright Office requires human authorship for registration. Its published guidance treats purely machine-generated output as unregistrable — a prompt alone generally isn't enough, because the Office's position is that prompts influence the output without controlling how it's expressed. Where a work mixes human and AI contributions, you can register the human parts, and you're expected to identify what's AI-generated when you apply.

The courts have now settled this. In Thaler v. Perlmutter, Stephen Thaler tried to register an image called "A Recent Entrance to Paradise," naming his AI system (the "Creativity Machine") as sole author. The D.C. Circuit ruled against him on 18 March 2025, holding that human authorship is required as a matter of statutory law — not merely as Copyright Office policy. The Supreme Court denied certiorari on 2 March 2026, which leaves that ruling standing as settled law in the United States.

So this is no longer an open question domestically: an AI system cannot be an author, and output with no human author cannot be registered.

Other jurisdictions differ, and if you're outside the US this matters:

• The UK has a provision for computer-generated works with no human author, attributing authorship to the person who made the arrangements for its creation — a notably different starting point.
• The EU generally requires the work to reflect the author's own intellectual creation, which points toward a human-authorship requirement similar to the US.
• China has gone the other way. In Li v. Liu (Beijing Internet Court, November 2023) — the country's first case on the copyrightability of AI-generated pictures — the plaintiff had produced images with Stable Diffusion. The court found the image copyrightable and the defendant liable for infringement, reasoning that the process reflected the plaintiff's aesthetic choices and personal judgement, and that he had invested intellectual effort from conception through final selection. That is close to the opposite of the US position on prompting.

So the same track can be registrable in one jurisdiction and not another. If where you operate matters to your plans, get advice from an actual lawyer rather than relying on any summary, including this one.

What "unregistrable" does and doesn't mean

This is the part that gets over-read. If you can't register copyright on a track:

You can still release it, distribute it, put it on Spotify, monetize it on YouTube, license it to clients, and collect streaming royalties. Registration isn't a prerequisite for any of that.

You can't easily sue someone for copying it. Copyright is your mechanism for stopping others from using your work, and without a registrable copyright that mechanism is weak or absent. In the US, registration is also a precondition for filing an infringement suit and for statutory damages.

So the practical consequence is narrow but real: your track can earn, but it's hard to defend as exclusively yours. For most releases that's an acceptable trade. If your track becomes the hook in an ad campaign, it isn't.

How to strengthen your position

Human contribution is what you're building. Each of these adds something a court could point at:

• Write the lyrics yourself. Lyrics are a separate copyrightable work from the recording. Human-written lyrics are protectable even if the music around them isn't.
• Do real editing. Arrangement decisions, cutting sections, restructuring, choosing takes from many generations — creative choices you made and can document.
• Mix and master. Your production work on the recording is your contribution.
• Add performance. Record a real instrument, sing a part, layer live elements.
• Keep records. Generation logs, session files, revision history, dated exports. If you ever need to demonstrate what you contributed, contemporaneous records are what does it.
• Be accurate when registering. If you do file, disclose the AI-generated portions and claim the human ones. Misrepresenting authorship can invalidate a registration.

A track where you wrote the lyrics, generated the instrumental, restructured the arrangement, and mixed it yourself is a substantially stronger position than a raw single-prompt export.

Royalty-free, copyright-free, public domain — not the same thing

These three get used interchangeably and mean completely different things. This trips up more people than the AI question does.

Term	What it means	Who owns it
Royalty-free	You pay once (or nothing) and owe no recurring per-use royalties. Still licensed, still has terms	Someone else
Copyright-free	Marketing language, not a legal category. Usually means royalty-free. Occasionally means public domain	Usually someone else
Public domain	Copyright has expired or was waived. Genuinely unowned	Nobody
Owned by you	You hold the rights outright	You

Two consequences worth internalising:

Royalty-free music is not free of restrictions. A royalty-free licence still specifies what you may do — some exclude broadcast, some exclude resale, some require the track not be the primary content. Violating those terms is infringement, price paid or not.

And public domain applies to compositions, not recordings. A Bach partita is public domain; a 2019 recording of it is not. This is the mistake behind a large share of the "but it's public domain!" copyright claims on YouTube.

For AI music specifically: generating your own track and holding the rights is a stronger position than licensing royalty-free library music, because you're not bound by someone else's licence terms.

How to check whether a song is copyrighted

Assume every recording is copyrighted unless you can show otherwise — that's the correct default, since protection is automatic on creation and requires no registration or notice.

To check a specific track:

1. Search a rights database. The US Copyright Office public catalog covers registered works. ASCAP, BMI, and SESAC repertory searches cover compositions and tell you the publisher. Absence of a record does not mean it's free to use.
2. Check the ISRC. The recording's unique identifier tells you who registered it.
3. Use YouTube's own check. Upload the video as private and see whether Content ID claims it. This is the fastest practical test for whether your use will be flagged in practice, and it costs nothing.
4. Check the licence you were given. If you got the track from a library, the licence terms are the answer — not a general search.
5. Estimate public domain status by date. Works published in the US before 1930 are generally public domain, and the boundary advances yearly. Recordings follow a separate and more complicated schedule than compositions. Non-US terms differ.

Where AI music genuinely can infringe

AI generation isn't a shield. Three real ways it produces a rights problem:

Voice cloning. Generating vocals that imitate an identifiable performer implicates rights beyond copyright — publicity and personality rights — and several jurisdictions have been tightening this specifically. Copyright registrability isn't the issue here; using someone's voice without permission is.

Regurgitation. A model can output audio close enough to a specific training example to constitute copying. It's uncommon but not theoretical, and it's most likely with distinctive short hooks.

Prompting for a specific artist's sound. Describing a genre is fine. Naming an artist and asking for their sound moves you toward derivative territory, particularly if the output is recognisably that artist.

The through-line: the more your output points at one identifiable person, the more legal exposure you have, regardless of what tool made it.

FAQ

Does Suno-generated music have copyright?

Your rights to the output come from Suno's terms for your plan, and paid tiers generally grant commercial use. Whether you can register copyright is a separate question governed by the human-authorship rule, and purely generated output typically can't be.

Do I own music I generate with AI?

Under most paid plans, yes, in the contractual sense — you can release and monetize it. Check your specific plan's terms for commercial use, exclusivity, and what happens if you cancel.

Can I copyright AI-generated music in the US?

Not the purely AI-generated parts. You can register human-authored elements — lyrics you wrote, your arrangement, your production — and you must disclose the AI-generated portions when applying.

Can I sell AI music commercially?

Yes, if your tool's terms allow commercial use. Registrability and saleability are separate issues.

Is AI music royalty-free?

Depends entirely on the tool. Some grant full ownership, some grant a limited licence. Read the terms; "royalty-free" and "yours" are not synonyms.

Will AI music get copyright claims on YouTube?

Sometimes, usually falsely. The most common cause is your own distributor having registered the track with Content ID, so it matches against your own recording.

Can I use AI to cover a copyrighted song?

Covering a composition requires a mechanical licence. Using AI to imitate the original performer's voice is a separate violation that a licence doesn't cover.

Does adding lyrics I wrote make it copyrightable?

It makes the lyrics copyrightable, and strengthens your claim over the work as a whole. It doesn't make the AI-generated audio itself registrable.

This is general information, not legal advice. AI copyright law is changing quickly and varies by country — consult a qualified lawyer before making decisions that depend on it.

Once you understand the rights picture, the next questions are usually practical: how to upload your music to Spotify and whether YouTube will monetize it.
