How do I extend a song with AI?

Pick a track from your library, choose the moment you want the song to continue from, and generate. The AI song extender picks up at that point and writes onwards, so a short sketch becomes a full-length song without you rewriting anything.

What does it cost to extend a Suno AI Music track?

Ten credits, the same as generating a new song, taken from the same balance. There is no separate export charge once the extended version is finished.

Does the extended part sound like the original?

It inherits the voice, key and arrangement of the source track by default, which is what keeps the join from being obvious. You can also override the style and lyrics for the new section if you want the song to change direction rather than simply continue.

Can I extend a song more than once?

Yes. The extended track lands in your library as its own song, so you can extend that one again and keep going. Each pass costs ten credits.

Which songs can I extend?

Any track in your own library — generated, covered, re-cut or previously extended. The song picker reads your library, so there is no upload for outside audio.

How long does extending take?

Usually one to three minutes. The job runs in your task list, so you can leave the page and collect the longer version when it is ready.
