What Is Royalty-Free Music? A Plain-English Guide

Royalty-free music is music you can use under a license without paying a royalty each time it is played, viewed or sold. You might pay once, pay a subscription, or pay nothing, but the rights holder doesn't collect a fee per use. It doesn't mean free, and it doesn't mean copyright-free.

Short answer

Royalty-free describes how you pay for music, not whether you pay or what you're allowed to do with it. Two things it does not mean:

• It doesn't mean free. Plenty of royalty-free music costs money. Wikipedia's entry on royalty-free puts it plainly: "When something has a royalty-free descriptor, that does not mean it is free."
• It doesn't mean copyright-free. Royalty-free music is still owned by someone. You're using it because a license lets you, and the license decides what you can do.

Where the word comes from

A royalty is a payment to a rights holder for each use: per copy sold, per broadcast, per stream. Royalty-free licensing drops that per-use meter. You get the right to use the track across many projects under one set of terms, which is why YouTubers, podcasters and game developers rely on it.

What to check in any royalty-free license

"Royalty-free" is a pricing model, not a license. Two sites can both call their music royalty-free and still have very different rules. Before you use a track, look for these six things:

1. Commercial use. Can you use it in ads, sponsored videos, client work, a paid app or a game? Some free libraries allow personal use only, or require a paid plan for commercial use.
2. Attribution. Do you have to credit the artist or the site? Creative Commons BY licenses require credit, and many library licenses don't. If credit is required, find out where it has to go (video description, end credits, app store listing).
3. Where you can use it. Some libraries are tied to one platform. YouTube's Audio Library, for example, lives inside YouTube Studio, and YouTube's help page about it covers use in YouTube videos.
4. Content ID and similar systems. On YouTube, rights holders who qualify can register their audio with Content ID. When a match is found, the claim can block the video, monetize it, or track its viewership. If a library's tracks are registered, you may need to have your channel cleared or dispute claims. Ask the library directly.
5. Resale and redistribution. Almost every library forbids repackaging its files and selling or giving them away as your own sound pack or stock library. Pixabay's license, for example, doesn't let you sell or distribute its content on a standalone basis.
6. Proof. If a claim or a client asks, what can you show? A license certificate, an account download history, or at least a link to the track page and the license text as it was when you downloaded.

Royalty-free vs public domain vs Creative Commons

• Public domain and CC0: no copyright restrictions, or they've been waived as far as the law allows. No license conditions and no credit required. Our explainer on CC0 vs CC BY goes into detail.
• Creative Commons (CC BY and its variants): standard public licenses. CC BY lets you use a work "for any purpose, even commercially," but you must "give appropriate credit, provide a link to the license, and indicate if changes were made." The NC variants forbid commercial use.
• Royalty-free library license: the site's own terms. Usually generous, but they vary, and it's the terms page, not the label, that counts.

A note on YouTube

Using licensed music doesn't automatically protect you from a claim. Rights holders who qualify can register audio with Content ID, so a track you licensed can still match someone else's registration. If you get a claim you believe is wrong, you can dispute it. YouTube lists "having all the necessary rights to the content in your video" as a reason to dispute, and "the claimant has 30 days to respond." Keep your license records somewhere you can find them. Our guide to AI music, copyright and Content ID walks through how claims work.

Royalty-free music and sound effects on Sonilo

Sonilo publishes two free libraries under its own library license. The two have different rules.

The royalty-free music library has 1,201 AI-generated tracks. Almost all are instrumental, a few have wordless vocals, and none has sung lyrics:

• Free to download in MP3 and WAV, with no account and no credit.
• The free download is for personal, non-commercial use. Commercial use, such as monetized videos, ads, sponsored content or client work, needs a Pro plan or above, with no revenue cap.
• Sonilo doesn't register library tracks with YouTube Content ID, so the track itself shouldn't trigger a claim. If one appears anyway, dispute it and link the track page. There's more in music for YouTube videos.

The royalty-free sound effects library has 3,463 AI-generated sounds in 66 categories:

• Free to download in MP3 and WAV and to use in personal and commercial projects: monetized videos, paid ads, client work, podcasts, apps and games.
• No account, no credit and no royalties. You can use the files inside your own projects, including games, apps and templates you sell, with no revenue cap.
• Sonilo doesn't register library sounds with YouTube Content ID.

Rules for both libraries: you can't sell or share the files on their own or in packs, and free downloads don't include a license certificate. Pro and Premium members can download a certificate for any library sound effect or music track.

If nothing in the library fits, every track page has a "Generate a variation" button that opens Sonilo's text-to-music generator. Generating needs an account and uses credits, and what you generate follows your plan's license (commercial use starts on Pro). Sonilo's models are trained on licensed catalogs, including Shutterstock's. More detail: Is Sonilo music royalty-free?

FAQ

Is royalty-free music free?

Not necessarily. Royalty-free describes how you pay (not per use), not whether you pay.

Can I use royalty-free music on YouTube and still monetize?

Usually, if the license allows commercial use. Check whether the library registers its tracks with Content ID and how it handles claims.

Do I have to credit royalty-free music?

Only if the license says so. CC BY tracks always need credit. Many library licenses don't.

Is royalty-free music the same as copyright-free music?

No. "Copyright-free" is mostly a search term. Royalty-free music is still under copyright or another license. Only public domain and CC0 works come close to having no restrictions.
