AI Music for Video: What the Licence Actually Covers

AI music generation is the most useful and the least settled part of the generative stack. You can produce a track that fits your edit in ninety seconds, which is genuinely better than searching a stock library for something adequate. The rights position is less clear than the tooling, and the difference between the licences on offer is larger than most people notice.

There are three distinct products in this category, and they are not interchangeable.

Three different things sold as "AI music"

Song generation with vocals. You prompt, it produces a full track with lyrics and a singer. This is the impressive demo and the hardest licence, because it produces something that resembles a commercial recording.

Instrumental scoring. You specify mood, length, and genre, and it produces a background score. This is what most video work needs, and the licence is usually clearer because there is no vocal performance involved.

Royalty-free library with generation. You pick from generated variations and download. The licence is closest to conventional stock music, because the vendor is explicitly selling a licence rather than a capability.

Most people who need music for a video want the second or third. The first is for musicians sketching ideas, and using it in a commercial video is where the licence questions get difficult.

The licence ladder

Read the terms in this order, because the differences are material:

Personal use only. Common on free tiers. You cannot put the output in anything you monetise, including a YouTube video with ads. This is the clause people breach accidentally.

Commercial use permitted. You can use it in monetised content. This is the minimum for most creators and it is usually on the paid tier.

Commercial use with restrictions. Permitted, but not in advertising, not in political content, not resold as music, or not in anything where the music is the primary content. Read the exclusions — they are where the real limits live.

Copyright assigned to you. You own the output. This is rare, it is the strongest position available, and it is usually a specific higher tier. One or two tools offer it deliberately as their differentiator.

No licence granted at all. A few tools reserve all rights and grant only a limited right to listen. Check this before assuming.

The practical question is narrow: does the licence cover my specific use? "Commercial use" in a terms-of-service summary is not the same as commercial use in your context.

The unsettled part, stated honestly

Copyright in AI-generated music is unresolved in most jurisdictions, and the music case is harder than the text case because:

• The training data is contested in a way that text training data is not, and there is active litigation.
• The output can resemble an existing recording, which is an infringement question rather than an authorship question.
• Performance rights organisations have taken positions on whether generated tracks can be registered.

What this means practically: a vendor granting you commercial rights is granting what it can grant. If the output resembles a protected work, the vendor's licence does not cure that, and indemnification for this specific risk is close to nonexistent in this category.

The mitigation is unglamorous. Use instrumental scoring rather than song generation, use a tool with a documented training-data position, and keep a record of the prompts and outputs. That is not a legal guarantee — nothing in this category is — but it is the position that survives a question.

What to check before a client deliverable

If the music is going into client work, four checks:

1. Does the licence permit commercial use at your tier? Free tiers usually do not.
2. Does it permit advertising use? Often excluded even on paid tiers, and client work is frequently advertising.
3. Can you assign or sublicense to the client? Some licences are non-transferable, which breaks a standard deliverable clause.
4. Does the client's own policy allow AI-generated assets? Some brands have an explicit prohibition, and it is not your licence to override.

The fourth one generates more awkward conversations than the other three combined, and it is a question to ask at the start of the engagement rather than at delivery.

Where the cheap option wins

For background music in a video where the music is not the point — a tutorial, a product walkthrough, an internal presentation — the royalty-free generation tools are excellent value. A few dollars a month buys unlimited downloads with a commercial licence and no attribution requirement, which is cheaper and faster than any stock library.

That is the realistic sweet spot: not song generation, but instrumental scoring with a clear licence. It covers most video work and it avoids most of the hard questions.

The mistake is reaching for song generation because the demo is impressive, then discovering the licence does not cover the use and the track cannot be shipped.

The compressed answer

Decide first whether you need a song or a score. If it is a score — which it usually is for video — the royalty-free generation tools are cheap, clearly licensed, and good enough. If it is a song, treat the output as a sketch rather than a deliverable until the rights position settles, and do not put it in anything a client will own.

For tool-by-tool detail, the AI music tools reviews record the commercial-use position and whether copyright assignment is available. Udio vs Suno compares the two song generators on licence terms rather than output quality, which is the axis that matters for shipping anything.
