cover_music generates a new style or arrangement over an existing song you have a URL for — your own upload or a prior generation — rather than writing a from-scratch new track. It's the tool for when the SONG is right but you want a different feel: a lo-fi cover of an upbeat original, an acoustic version, a different vocal tone.
Once generated, attach it to your video the same way as any other music track.
Powered by
Generate a Suno cover/reinterpretation of an existing audio track from its URL (new style/arrangement over the same song). Use when the user wants a cover version of a track they have a URL for (their own upload or a prior generation), not a from-scratch new song.
What to tell the agent
Versely's agent maps this plain-English request directly onto cover_music. You don't need to know the parameter names — just describe what you want.
“Generate an acoustic cover of this track, then mix it under my video at low volume.”
How it works
1. Point to the source track
audioUrl needs to reference an existing track — your own upload or a prior generation.
2. Describe the new arrangement
prompt and style describe the direction for the cover; instrumental skips vocals if you just want the reinterpreted instrumentation.
3. Generate
Versely produces a Suno-based cover in the new style.
4. Attach to your video
Use attach_audio_to_video (mix or replace) to lay the cover onto your footage.
What it costs
Billed per cover generated, similar to a standard generate_music call. Confirm the exact price with estimate_cost.
The formula behind that number: What does a finished 30-second AI ad cost end to end? — sums four unrelated meters, so no single rate predicts the total.
Limits & things to know
- Requires a URL to an existing track — this reinterprets a song you already have, it doesn't write a brand-new one from a blank prompt (that's generate_music).
- Rights to the source song still matter — cover generation doesn't itself confer commercial rights to a third-party original.
Who uses this
- Reinterpreting a track's mood for a different video style
- Acoustic or stripped-down versions of an upbeat original
- Matching a song's arrangement to a video's pacing
Frequently asked questions
Does this write a new song or reinterpret an existing one?+
It reinterprets an existing track you point it to via audioUrl — a new style or arrangement over the same song, not a from-scratch composition. For a brand-new song, use generate_music instead.
Can I get an instrumental-only cover?+
Yes — set instrumental to skip vocals and get just the reinterpreted arrangement.
