Fix One Weak Section Without Rebuilding the Entire Song
Use Replace Song Section when most of the track already works and only one chorus, verse, or transition is dragging the whole result down.

Why Replace Only the Weak Part
When most of the song already works, targeted repair is more efficient than restarting from zero.
Repair the failure point only
Focus on the weak section instead of throwing away the verses, arrangement, or texture that already worked.
Keep the song identity intact
Section-level replacement preserves more continuity than full regeneration.
Work with explicit timing
Define the exact time window so the model knows where the repair starts and ends.
Use credits more intentionally
Spend repair credits on songs that are already close, not on tracks you will discard anyway.
How It Works
Three steps from almost-good song to cleaner result.
Choose the source song
Start from a generated track that mostly works except for one weak section.
Define the time range and direction
Set the start and end time, then describe what the replacement should sound like.
Generate the revised version
Review the new result and decide whether the song now clears the quality bar to keep.
Where Section Replacement Helps Most
Typical moments where targeted repair beats full regeneration.
Chorus repair
Chorus repair
Replace a weak hook without losing the rest of the song
Use section replacement when the chorus missed but the verses and production already work.
Bridge rewrite
Bridge rewrite
Repair a transition that breaks momentum
Rewrite the section where pacing falls apart while keeping the stronger surrounding material.
Late-stage polish
Late-stage polish
Refine a nearly-finished track instead of restarting
Use the tool when the track is already close enough that full regeneration would be wasteful.
This tool is best when the song is already mostly right and only one section is not.
Use Section Replacement Only When Most of the Song Has Already Earned Protection
The real savings come when you protect the parts that already worked and spend credits only on the weak section.
Repair instead of discard
Use credits on targeted revision when the rest of the arrangement is already good enough to preserve.
Know when not to use it
If the whole song misses the brief, a clean new generation is usually the better move.
Keep polished tracks moving forward
Section repair is a late-stage workflow for songs that are already close to done.
