Change Song Lyrics
How do you change the lyrics of a song with AI?
Upload your song (MP3, WAV and other common formats up to 50MB) or pick one from your RaoMusic library. Paste the lyrics so each line can be matched to the vocals, drag over the section to change (10 to 60 seconds, up to half the song), and type the new words. AI re-sings that section in the same style and returns two versions in about a minute. It works on the free plan: one run on the default model costs 20 credits.
No subscription required
Works on the free plan, MP3 download included. 50 free credits every month.
Works on uploaded songs
Not just songs made here: upload your own MP3 or WAV and edit it.
Fix one part without redoing the song
Change lyrics with AI vs re-recording vs regenerating
Editing one section keeps the song you like. Re-recording takes a singer and a session. Regenerating gives you a different song.

How to change the lyrics of a song

When to change lyrics with AI
Use it when the song works and only some words don't. Skip it when you want a different song or an exact match of a real singer.
Best for
- ✓Fixing a line or a verse after the song is done
- ✓Swapping a name or detail to personalize a song
- ✓Testing an alternative chorus or hook
Not for
- !Rewriting most of the song (generate a new one instead)
- !Matching a specific real singer's voice exactly
- !Instrumentals with no vocals
How AI changes the lyrics in part of a song
People use it to fix a line that doesn't land, swap a name to personalize a song, clean up a lyric before release, or test an alternative hook without paying for a new session. Because you can upload your own file, the song does not have to come from RaoMusic.
The AI regenerates only the range you select, keeping 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, change lyrics with a similar number of syllables, start and end the range at natural line breaks, and keep the section under a minute. If a take misses, adjust the words or the range and generate again.
