Best AI Music Generator for Video in 2026
Three tools, three completely different pricing shapes. Pick the shape that matches how you work and the rest follows.
Most “best AI music generator” lists rank tools by how good the output sounds. For video work that is the wrong first question. They all sound broadly fine now, and none of them sound like what you wanted on the first try.
What actually decides it is shape: how the tool charges you, where commercial rights begin, and whether you get stems.
A new option just landed that makes the pricing question sharper than it was. Google Lyria 3.5 is live in MITO, and it charges a flat fee per generation regardless of length.
What Lyria 3.5 brings to the table
You can steer it. Tempo, instruments, vocal style, song structure, down to timing cues for builds and transitions. Before, you described a mood and hoped.
Vocals stopped sounding robotic. They are more expressive, and the model takes image prompts, so you can point it at a scene and have the music follow its visual mood.
Tracks run to three minutes. As one continuous piece, not short clips you stitch together afterwards.
The three pricing shapes
Every tool in this category prices itself one of three ways, and the difference matters more than any feature.
| Shape | What you pay | Suits |
|---|---|---|
| Per generation, flat | Same price at any length | Long cues, few revisions |
| Per second | Scales with duration | Short stings, heavy iteration |
| Subscription | Monthly credit allowance | Steady daily volume |
Inside MITO the first two sit side by side, which makes the comparison concrete:
| Lyria 3.5 | ElevenLabs Music | |
|---|---|---|
| Pricing | Fixed, any length | 9 credits per second |
| 10 seconds | 80 credits | 90 credits |
| 60 seconds | 80 credits | 540 credits |
| 3 minutes | 80 credits | 1,620 credits |
The crossover is about nine seconds. Under that, per-second wins. Over it, flat wins, and the gap widens fast.
Suno and ElevenLabs sold direct both work the third way: a monthly fee buys a credit allowance you draw down.
Where commercial rights actually begin
This is the most-asked question in the category and the one most comparisons skip.
On a free plan you generally do not have commercial rights. Suno’s free plan lists “No commercial rights” outright. ElevenLabs includes a commercial licence and music commercial use from its Starter plan, not on free.
The practical rule: free tiers are for auditioning the model. The moment a track goes near a client you need to be on a paid plan, and you need to have read that plan’s terms. This is not a detail to sort out after the edit is locked.
Two further things a brand’s legal team will ask before they ask about sound:
What was it trained on? Google states Lyria was trained on licensed material that YouTube and Google had rights to use, and blocks prompts for named artists’ voices and copyrighted lyrics. Not every model makes that claim, and the ones that do not are a harder conversation.
Is it watermarked? Lyria output carries SynthID, an imperceptible marker designed to survive re-encoding. It identifies audio as AI-generated. Worth saying plainly: it is not a licence and it clears nothing.
Stems, and why they decide it for video
For a song, a stereo mix is the deliverable. For video, it usually is not.
The moment there is a voiceover you need to duck the music under it, and doing that on a flat mix means fighting the whole track instead of pulling one element down. Stems are the difference between a five-minute fix and a re-generate.
Suno separates stems on paid plans: two types on Pro, three on Premier. If a tool does not offer stems, that is a real constraint on client work, whatever it sounds like.
Length, and the review cost nobody budgets
A three-minute cue generated as one continuous piece holds under a long sequence without an obvious loop point. That is the case for Lyria’s length.
The cost nobody plans for: a three-minute track takes three minutes to actually listen to before you can approve it. On a flat per-generation price there is no reason not to generate the full length, so budget the review time. Two rounds on a three-minute cue is twelve minutes of listening, not two.
The same flat fee cuts the other way on short work. If you are iterating on a four-second sting you pay full freight every regeneration, so write a longer prompt and get further in one pass rather than nudging it repeatedly.
So which one
Scoring a film, a brand piece, anything over about a minute. Flat per-generation pricing, so Lyria 3.5. The length is free and the number does not move.
Short stings, UI sounds, social cutdowns under ten seconds. Per-second pricing is genuinely cheaper, so ElevenLabs Music. Below the crossover the maths favours it.
Producing music all day, every day, as the main job. A subscription with a monthly allowance fits better than per-use pricing, so Suno or ElevenLabs direct. You are optimising for volume, not per-track cost.
Client work of any kind. Whichever tool you pick, be on a paid plan, get stems, and be able to answer the provenance question before anyone asks it.
A note on prices
Every figure a comparison post quotes goes stale, and vendor pricing varies by region and by monthly versus annual billing. Suno’s page quotes euros in Europe and dollars in the US, for the same plan. Check the vendor’s own page in your currency before you commit: Suno, ElevenLabs.
The pricing shapes change far more slowly than the numbers, which is why this post is built on those.
Lyria 3.5 and ElevenLabs Music both run inside MITO, so you can switch between the two pricing shapes without switching tools.
Frequently asked
- Which AI music generator is best for video?
It depends on how you work rather than which model sounds best. If you generate long cues and iterate rarely, a flat per-generation price like Lyria 3.5 is cheapest. If you make lots of short stings, per-second pricing costs less. If you are producing music all day, a subscription with a monthly credit allowance fits better.
- Can I use AI-generated music commercially?
Only on a paid plan, on every major tool. Suno’s free plan explicitly excludes commercial rights, and ElevenLabs grants a commercial licence from its Starter plan up. Free tiers are for trying the model, not for client work. Always check the terms of the specific plan you are on before you ship.
- How much does AI music generation cost?
It depends on the pricing shape. Per-generation pricing charges the same whatever the length. Per-second pricing scales with duration. Subscriptions give you a monthly credit allowance. Published prices also vary by region and by monthly versus annual billing, so check the vendor’s own page for your currency.
- What is Google Lyria 3.5?
Lyria 3.5 is Google’s music generation model, available in MITO. It generates instrumental and vocal music from a prompt, up to three minutes as a single continuous track, and costs 80 credits per generation whatever the length.
- Can I control the structure of the track?
In Lyria 3.5, yes. You can steer tempo, instruments, vocal style and song structure, including timing cues for builds and transitions, rather than describing a mood and hoping. It also accepts image prompts, so you can point it at a scene and have the music follow that visual mood.
- Do I get stems, or just a finished mix?
Stems matter for video because you usually need to duck the music under a voiceover. Suno includes two stem separation types on Pro and three on Premier. Check for stems before committing to a tool for client work; a flat stereo mix is much harder to edit around dialogue.
- Is AI-generated music watermarked?
Google watermarks Lyria output with SynthID, an imperceptible marker designed to survive re-encoding. It identifies the audio as AI-generated. It is not a licence and it does not clear anything.
- What was the model trained on?
Worth asking, and the answers differ. Google states Lyria was trained on licensed material that YouTube and Google had rights to use, and blocks prompts for named artists’ voices and copyrighted lyrics. For client work, a brand’s legal team usually asks about provenance before it asks about sound quality.
- How long can a track be?
Lyria 3.5 goes up to three minutes, generated as one continuous piece rather than short clips you stitch together. That matters when a cue has to hold under a long sequence without an obvious loop point.
