AI music generation is the use of models that turn a text prompt, a reference track or a melody into finished audio. In client campaigns it works best for drafts, short social edits and background beds where a stock library would otherwise be used. Hero brand anthems and anything with a recognisable artist style still need a human composer and careful licensing.
The best-known consumer tools at the time of writing include Suno and Udio, which produce full songs with vocals, and Stable Audio from Stability AI, which focuses on instrumental and sound design. Google has shown music models such as Lyria, and video editors including Adobe and CapCut are adding generated soundtracks. Quality has improved fast, but the legal side has moved more slowly.
What can AI music tools do well today?
Text-to-music tools are strong at mood. Ask for “upbeat acoustic guitar, 100 BPM, warm, no vocals, 30 seconds” and you will usually get something usable in a few tries. They are also good at variations: the same track in a shorter cut, a calmer version or a different instrument mix.
They are weaker at structure and precision. Hitting an exact beat for a logo reveal, matching a 6-second bumper cut or keeping a melody consistent across ten assets often takes many generations, or a human editor in a digital audio workstation afterward. Lyrics can come out clumsy, and vocals may carry artefacts that sound fine on a phone speaker and odd on headphones.
Where does generated music fit in a campaign?
Not every asset deserves the same budget. A useful way to plan is to sort assets by visibility and lifespan.
- Internal pitch videos and animatics: generated music is usually fine and saves licence fees on drafts
- Organic social clips with a short life: generated beds can replace stock tracks, after a licence check
- Paid social and pre-roll ads: possible, but run a stricter rights review because of wider reach
- TV, cinema and brand anthems: commission a composer; the asset carries the brand for years
- Podcasts and webinars: generated intro and outro stings work well when kept simple
Which licensing questions must be answered first?
This is the step agencies cannot skip. Each tool has its own terms, and those terms often differ between free and paid plans. On some free tiers, the platform keeps ownership or limits commercial use. Paid plans usually grant commercial rights, but the details vary and change over time.
There is also open legal debate about training data. Major record labels have taken legal action against some music AI companies over the use of recordings in training, and outcomes were still developing at the time of writing. Copyright offices in several countries have also said that purely machine-generated output may not qualify for copyright protection, which means a brand might not be able to stop others from reusing the same track.
A rights checklist per track
- Plan in use and the exact commercial terms on the day of generation, saved as a PDF
- Who owns the output and whether the platform can reuse it
- Whether the prompt named a real artist or song (avoid it entirely)
- Whether the track will be registered with Content ID or similar systems
- Client approval of the risk level in writing for paid media
How do you brief an AI music tool like a composer?
Good results come from good briefs. Write a short sound brief before opening the tool, and reuse it so every asset in the campaign sounds related.
Include tempo range, key mood words, instruments to use and avoid, length, energy curve (for example, “quiet start, lift at 8 seconds, hold to end”) and whether vocals are allowed. Add references described in words rather than artist names. “Bright synth pop with handclaps” is a safer prompt than naming a chart act, and it usually produces more original results anyway.
Quality control before anything goes live
Listen on three systems: phone speaker, laptop and headphones. Artefacts that disappear on a phone can be obvious on headphones, and the reverse happens with harsh high frequencies.
Check loudness against platform norms. Streaming and social platforms normalise audio, and a track mastered too loud will be turned down and may sound flat next to the voiceover. Many editors aim for integrated loudness around minus 14 LUFS for online video, while broadcast follows stricter standards such as EBU R128. Finally, run the track through a reverse audio search or upload it as a private video to see whether any platform flags a match.
How Alien Road applies AI music generation
In a typical engagement, discovery covers the client’s existing sound assets, if any, and the media plan. We decide together which assets can use generated music and which need a composer or a licensed library track, based on reach and lifespan.
Setup means a sound brief, a chosen tool on a paid plan with commercial terms saved for the record, and a naming system for every generated file that links back to its prompt and date. Production teams generate several options, shortlist three and edit the winner in a workstation for timing. Measurement is simple but useful: we compare completion rates and engagement for ad variants with different tracks, and we report any claim or flag received on the platforms. Paid media use always waits for written client approval of the rights position.
When should you hire a composer instead?
Hire a person when the music will define the brand, when it needs to work across years of campaigns, or when you need clear ownership you can register and defend. A sonic logo is the obvious case. So is any campaign where the music is the idea, not the background.
Some teams combine both. A composer writes the main theme, and AI tools help produce quick variations for social cutdowns under the composer’s direction. That keeps ownership clear and still speeds up the volume work.
Where to start this week
Write a one-page sound brief for your brand: tempo, mood words, instruments and things to avoid. Then generate five 30-second beds in a tool on a paid plan, and save the terms page as a PDF on the same day.
Test two of those beds against your current stock track in an organic social post. If the generated version performs at least as well and passes the rights checklist, you have a low-risk place to use AI music while the legal picture settles.
