Extend a song with AI

Pick a song you made here and the second it should carry on from. Add the next verse or let the music play on, and get two longer versions.

Choose one of your songs, play it and stop where the new part should start, then add lyrics or leave them empty. In about a minute you get two versions, each the whole song with the new part on the end. It costs 10 credits. To fix one part instead, Replace part sings 10 seconds up to half the song again with new words, for 5 credits. The original is never changed.

Questions about extending a song with AI

Can I extend a song I didn’t make here?

No. Extend and Replace part work only on songs made here, because the song maker carries on its own songs. To use an outside song, try a cover instead.

How long does the extended song get?

About as long as the new part needs. Our 29-second test song came back at 57 and 58 seconds after one extend from 0:28. Extend again to make it longer.

Does extending change my original song?

No. The two new versions are added to your library as new songs, and the original stays as it was.

What does it cost to replace a section of a song?

5 credits for two takes. If the run fails, the credits come back.

Can I extend an instrumental?

Yes. Leave the lyrics empty and the music carries on in the same style.
