Credit Cost
Each replacement costs 10 credits. Pick a 6-60 second window to rewrite.
Fix Any Section
Replace a 6-60 second window of your song with freshly generated lyrics and vocals
Each run produces two takes, saved to your library
Fix One Section, Keep the Rest
Replace Section rewrites a 6-60 second window of a song from your library — new lyrics, new vocals — while everything outside that window stays exactly as it was. Fix a weak chorus, correct a line that came out wrong, or try a different idea without regenerating the whole song.
Pick the Exact Window
Drag out any 6-60 second span on the timeline. Only that stretch is touched.
New Lyrics, Same Voice
Type what the section should say. The vocals are regenerated in the style of the original performance.
Everything Else Untouched
Verses, hooks, and production outside the window are kept exactly as they were.
Two Takes per Run
Each replacement costs 10 credits and returns two versions — keep the one that sits best in context.
Spend Credits Where It Counts
Fix the one weak section instead of burning full regenerations hoping the good parts survive.
Commercial Use
Replaced sections stay copyright-free and carry the same commercial licence as the original song.
Common Use Case
Replace Music in a Weak Chorus
Your hook needs work
You generated a banger verse. Then the chorus lands flat. Before, your only option was regenerating the whole song and hoping the verse came out just as good. Now you replace just the chorus. The verse stays exactly the same. Try until the hook actually hooks.
Fix Lyrics
Replace Music With Wrong Words
AI wrote something weird
The melody is great but the AI generated nonsense lyrics or mispronounced something. Write the new words for that section, then replace it. Same song, your words, sung correctly.
Fix Pacing
Replace Music That Drags
A section kills the momentum
That bridge goes on forever. The outro puts people to sleep. Replace slow sections with something energetic. Build where it should build. You control the flow.
Experiment
Replace Music to Try New Ideas
What if you went a different direction
What if the bridge was acoustic instead of electric? What if the chorus had more bass? Replace any section to experiment. Your original song stays saved — if the experiment works, keep it. If not, try again.
