AI Song Editor: Replace One Part of Your Song

Love the song but not one line? Select that part on the waveform, change the words or keep them, and regenerate just that section.

Generating a whole new song to fix a single verse throws away everything you liked. The song editor keeps the song and rebuilds only the part you select, blending it back into what comes before and after.

Use it to rewrite a lyric, fix a stumbled word or a rough transition, or simply hear a different take of a chorus. Every edit is saved as a new song, so the original is never overwritten.

How to replace part of a song

  1. 1

    Choose one of your songs

    Pick a song from your Musikalis library. The editor loads its waveform, style and lyrics.

  2. 2

    Select the part to replace

    Drag the handles on the waveform. A section is at least 10 seconds and at most half the song; press play to hear exactly what you selected.

  3. 3

    Edit the lyrics and generate

    Rewrite the lines sung in that part, or leave the lyrics as they are for a fresh take. Generate and compare the two new versions.

What stays and what changes

Only the selected part is regenerated. Everything before and after it is kept from your original song, with a short crossfade on each side so the new part blends in.

  • The song keeps its length, structure and style.
  • New lyrics are sung in the selected part; unchanged lyrics give a new performance of the same lines.
  • Each edit creates two new versions in your library.
  • Your original song is never modified.

Choosing a good section

Start and end the selection a little before and after the line you want to change, ideally at a pause between phrases. Keep the rest of the lyrics as they are so the edited part still fits the song.

Frequently asked questions

Which songs can I edit?

Songs in your Musikalis library that are at least 20 seconds long, because a section must be at least 10 seconds and no more than half of the song.

Will my original song change?

No. Every edit is saved as a new song with two versions; the original stays in your library unchanged.

Do I have to change the lyrics?

No. If you leave the lyrics as they are, the selected part is performed again with the same words, which is useful for fixing a rough take.

Which plans include the song editor?

The song editor is included in the Pro and Enterprise plans. The credit price is shown on the button before you generate, and failed edits are refunded.
