How do you fix one part of an AI song without regenerating it?

Upload the song (MP3, WAV and other common formats up to 50MB) and paste its lyrics, or pick a song from your RaoMusic library. Click Sync lyrics and the words are lined up with the vocals in about a minute, free. Then select the part to fix, 10 to 60 seconds and up to half the song. Correct the words, or leave them as they are to get a fresh take of a glitchy line. AI re-sings that section in the same style and returns two versions. One run on the default model costs 20 credits, and free accounts get 50 credits every month. As of November 2026, Suno lists its own Replace Section for Pro and Premier subscribers; here it works on the free plan.

  • No subscription required

    Works on the free plan, MP3 download included. 50 free credits every month.

  • Works on songs made elsewhere

    Upload the MP3 from Suno or another AI tool. The song doesn't have to be made here.

How do you fix one part of an AI song without regenerating it?

Keep the song, fix the part

Fix a wrong or mispronounced word

Select the line with the mistake, at least 10 seconds around it, type the correct word, and AI re-sings that line. The smallest edit is about one line, not a single syllable.

Redo a weak verse, chorus or bridge

Keep the lyrics or rewrite them. Drag over up to 60 seconds and get a new take of just that part, in the same voice and style.

Two versions, the rest kept

Each run returns two blended versions. Compare them in your library, download the MP3, and fix another part on the new version if you need to.

Fix one part vs regenerate vs re-record

Fixing a section keeps the song you like. Regenerating gives you a different song. Re-recording takes a singer and a session.

  • Keeps the rest of the song

    • Fix one part with AI:Yes
    • Regenerate the whole song:No
    • Re-record the part:Yes, after mixing

  • Works on songs made with other tools

    • Fix one part with AI:Yes, upload the MP3
    • Regenerate the whole song:Only in the tool that made it
    • Re-record the part:Yes

  • Needs a singer

    • Fix one part with AI:No
    • Regenerate the whole song:No
    • Re-record the part:Yes

  • Turnaround

    • Fix one part with AI:About a minute
    • Regenerate the whole song:About a minute
    • Re-record the part:Hours to days

How to fix part of an AI song

Three steps. No re-recording, no new song from scratch.

  1. 1

    Upload or choose the song

    Sign in, upload the MP3 and paste its full lyrics in the box below, or pick a song from your library. Click Sync lyrics; matching the words to the vocals is free.

  2. 2

    Select the part and set the words

    Drag over the part to fix, 10 to 60 seconds. Correct the words, or leave them unchanged for a fresh take.

  3. 3

    Generate, compare, download

    Listen to both versions in your library and download the one that fits. Not right yet? Move the range or adjust the words and run it again.

When to fix part of a song with AI

Use it when the song works and one part doesn't. Skip it for songs you don't have the rights to, or when you want a different song.

Best for

  • ✓A wrong or mispronounced word in an AI song
  • ✓A glitchy, mumbled or off-key line
  • ✓A weak verse, chorus or bridge in an otherwise good song

Not for

  • !Released songs by other artists (stopped by copyright checks)
  • !Rewriting most of the song (generate a new one instead)
  • !Changing one syllable without touching the rest of the line

Why fix one part instead of regenerating the song

Regenerating a whole AI song to fix one word usually costs you the parts you liked: the melody, the voice, the take that worked. Fixing a section keeps all of that and replaces only what's wrong, whether it's a misspelled name, a mumbled line, a glitch in the vocal or a chorus that falls flat.

The AI regenerates the range you select, keeps the tempo, key and vocal style of the song, and blends the new section into what comes before and after. The output is a new render of the full track, so tiny differences outside the edited part are possible; most of the time the rest sounds the same.

For the best result, start and end the selection at natural line breaks, keep corrected lines at a similar number of syllables, and spell names the way they're pronounced. If a take misses, move the range a little or tweak the words and try again.

Yes, but the AI re-sings at least 10 seconds, so select the line around the word, usually one or two lines. Type the corrected word and keep the rest of the line as it is. The rest of the song keeps its lyrics and melody.

Yes. Download the MP3 from the other tool, upload it here (MP3, WAV, OGG, M4A or AAC up to 50MB) and paste its lyrics. RaoMusic is an independent service and isn't affiliated with Suno.

As of November 2026, Suno's help center lists Replace Section for Pro and Premier subscribers. Here it works on the free plan: one run on the default model costs 20 credits, and free accounts get 50 credits a month. Check Suno's current plans before you compare.

20 credits per run on the default model, and each run returns two versions. Free accounts get 50 credits every month, enough for two fixes. If a run fails, the credits are refunded automatically.

Between 10 and 60 seconds, and no more than half of the song. To fix more, fix one part, then run it again on the new version.

The parts outside your selection keep their lyrics, melody and arrangement. The whole track is re-rendered so the new section blends in, which can cause very small differences; each run gives two versions to choose from.

Yes. Leave the words as they are and generate. You get a fresh take of that section, which helps with glitchy, mumbled or off-key lines.

Songs you made on RaoMusic, and your own original songs that you upload, can be used commercially, even on the free plan. For a song made with another tool, that tool's terms still apply: Suno, for example, says songs made on its free plan can't be used commercially, and fixing them here doesn't change that.

This only works on songs you have the rights to. Uploads that match a released recording, or contain its copyrighted lyrics, are stopped, and any credits used are refunded. Use your own songs or AI songs you made.

Uploaded songs and songs made with the default model can be fixed. Songs made with some other engines in the model menu, such as Mureka, MiniMax or ElevenLabs, can't, and neither can instrumentals with no vocals or sound effects.
