Suno Cover Songs: Upload Rules and Rejected Audio Fixes

Updated 2026-09-10 · Suno-API team

Learn how to make a Suno cover song, the 10MB upload limit, and what to do when your audio is rejected. Covers cost 0.6 yuan each.

Cover songs are one of the most-used features on the site, priced at 0.6 yuan per run. The whole process runs in the browser, with no extra tools needed.

How a cover song works

  1. In the workspace, choose to upload audio, or pick an existing track from your works.
  2. Fill in the lyrics, style, title and other details.
  3. Submit the generation and wait for the task to finish.

Keep the uploaded audio under 10MB. After you submit, the system detects the lyrics and style automatically, and you can keep editing from there.

Why an upload gets rejected

The most common reason is that the uploaded audio is judged to contain copyrighted content. The review looks at the material itself, not your account, so swapping in a different piece of audio usually passes.

What to do after a rejection

  • Prefer audio you recorded yourself, performed yourself, or have been authorized to use.
  • If it is your own original song and it still gets rejected, you can use the platform's assisted upload channel, which covers most rejection cases.
  • Even if a cover of someone else's copyrighted song uploads successfully, it is not covered by commercial licensing. Do not use it for commercial delivery.
