Public domain and Creative Commons music: what is actually free

A public domain composition and a free recording of it are two completely different things, and confusing them is the most common expensive mistake in this area. Beethoven's Fifth is free. The Berlin Philharmonic's recording of it is not, and using that recording in a video will get you a claim from a rights holder who is entirely correct.

Here is what is actually free, how the licences work, and the specific traps.

Two rights, two clocks

Every piece of recorded music carries two separate copyrights, and they expire on different schedules.

The composition, meaning melody and lyrics, written by a composer. This is what enters the public domain after a term based on the composer's life.

The sound recording, meaning a specific performance captured on a specific day. Owned separately, with its own term, and almost always still protected even when the composition is not.

So the practical rule: a public domain composition gives you the right to perform, arrange and record it yourself. It gives you nothing at all regarding anyone else's recording of it.

This is the same two-rights structure that decides what you need to release a cover, and it is worth learning once because it explains most licensing questions.

Terms vary by country, and there is no single answer

Copyright terms differ by jurisdiction, and they have been extended repeatedly. Rather than quoting a number that may be wrong where you are:

Check the specific work in your own country. A composition in the public domain in one territory may still be protected in another, and publishing on the internet means publishing in all of them.

Old does not mean free. A nineteenth-century composition is very likely free. A specific edition or arrangement of it published last year may carry its own new copyright, because arrangements are protectable.

Recordings are the long pole. Even genuinely ancient compositions have recordings made recently, and those are protected.

Databases and library catalogues that track public domain status exist and are more reliable than assumption. When in doubt, treat it as protected.

Creative Commons, decoded

Creative Commons is not one licence. It is a family, and the differences matter enormously.

CC0. The author has waived rights as far as legally possible. Effectively free for any use, including commercial, with no attribution required. This is the only variant that behaves the way people assume "free" behaves.

CC BY. Free to use, including commercially, provided you attribute correctly. Attribution requirements are specific, and a video description saying "music from the internet" does not satisfy them.

CC BY-SA. Same, plus derivative works must carry the same licence. This is the one that surprises commercial users, because it can propagate obligations into your own work.

CC BY-NC. Non-commercial only. This means no monetised videos, no client work, no advertising. A monetised channel is commercial use even if you personally feel like a hobbyist.

CC BY-ND. No derivatives. You cannot edit, trim or remix it, which rules out most video use.

Two rules that prevent almost every failure here:

Read the actual licence on the actual file, not the site's general description. Individual tracks on aggregator sites carry different licences.

Screenshot the licence at the time you download. Licences get changed and files get reuploaded, and your evidence that a track was CC0 when you used it is worth having.

The traps, ranked by how often they bite

Assuming public domain composition means free recording. Covered above, and it is the big one.

Attribution done casually. CC BY requires specific credit. Getting it wrong converts a legal use into an infringing one.

Non-commercial creep. Your channel gets monetised, your old videos are still up, and their music was NC-licensed. The use became commercial retroactively from the licence's point of view.

Aggregator sites with unclear provenance. Someone uploads a track claiming it is CC0 when it is not. The uploader's claim does not transfer rights they never held, and you inherit the problem.

Content matching flags anyway. Even legitimately free music gets auto-claimed on video platforms because someone else registered it in a rights database. You can dispute it, which costs you time on a delivery you already made.

That last point is a real practical argument that gets underweighted: free is not the same as frictionless.

Where generated music sits in this picture

Generated music is a different mechanism entirely, and it solves a specific subset of these problems.

No attribution requirement, because you are not using someone else's work.

No content-matching claims, because your track is not in any rights database. This is a genuine advantage over popular free-library music that thousands of others are also using.

No provenance risk from a mystery uploader.

But rights are not automatic. On Suno, commercial use requires the song to have been made while you held an active paid plan, and it is not retroactive. That is a licence condition rather than a public domain freedom, and the rule catches people constantly.

And a licence is not a copyright. Being permitted to use a track is different from owning one, and under the US Copyright Office's position prompting alone does not create authorship. The distinction applies here as everywhere.

For a working comparison of the free and paid routes for video and content work, the alternatives to subscription libraries covers where each option runs out.

A decision rule

Personal, non-commercial, no distribution. Almost anything works, including NC-licensed material.

Monetised content. CC0 or CC BY with careful attribution, a commercial library, or music you made. NC is out.

Client work. Whatever you can document. Screenshot licences, keep records, and prefer sources with clear provenance.

Anything where sameness costs you. Generated or commissioned, because every free library is shared with everyone else. Our catalogue exists for the case where you want a specific sound rather than a shared one, with ten recipes open free.

FAQ

Is public domain music free to use? The composition is, once its term has expired in your country. A specific recording of it usually is not.

What does CC0 mean? The author has waived rights as far as possible, so the work is usable for any purpose including commercial, with no attribution required.

Can I use CC BY-NC music on a monetised channel? No. Monetised content is commercial use regardless of how you think of yourself.

How do I attribute Creative Commons music? Follow the specific licence's requirement, which usually names the title, author, source and licence. Vague credit does not satisfy it.

Why did free music get a copyright claim? Content matching is triggered by rights databases rather than by the licence you hold. Legitimate use can still be flagged and needs disputing.

Is AI-generated music public domain? No. It is governed by the platform's licence terms, and its copyright status depends on how much human authorship is present.
