Replace Any Song Section
Select a finished song, drag the exact range on the waveform, rewrite the lyrics or style direction, and generate a new version that keeps the rest of the track intact.
How to replace a song section
A focused workflow for repairing one part of a generated track without starting over.
Choose a source song
Start from a completed track in your music library, or jump in directly from My Works and the preview panel.
Mark the section
Drag the waveform selection, resize the edges, or click a detected song section such as intro, verse, or hook.
Rewrite and generate
Review the current lyrics, write the replacement lyrics or direction, then generate a repaired version.
Precise AI track segment editor -edit at exact timing points
Our Replace Section tool uses direct waveform selection instead of generic prompt bounding boxes. Drag your selected range, adjust start/end handles, and lock edits to the exact song section you need to refine.
Lyric-tied editing -adjust only your chosen lyrical lines
Your editor displays lyrics tied to your selected time range, with a dedicated focused edit workspace. If you adjust your selection post-edit, a draft warning will prompt you before submitting mismatched lyrical content.

Precise AI generation range controls -keep edits sharply targeted
Replacement ranges are limited to practical editing windows to keep your task focused and consistent. The draft preview panel breaks down track duration, lyric line count, style tags, and merge readiness before you run generation.
