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.
AI song section editor -work on the exact moment
Replace Section is built around direct waveform selection instead of a generic prompt box. Move the selected range, adjust the start and end handles, and keep the edit locked to the part of the song you actually want to change.
Lyric-aware replacement -rewrite only the selected lines
The editor shows the lyrics inside the selected time range, then gives you a focused replacement area. When the selection changes after editing, the draft check warns you before you submit mismatched lyrics.

Instrumental
Connected to your works -start editing from where you listen
Use Replace Section from the dedicated page, from My Works, or from the music preview panel. The selected song opens in the editor so you can repair weak lines, swap an intro, or test a new hook quickly.
Make songs from an idea, not a DAW.
Prompt, generate, extend, and export in one workflow built for creators who need music fast.
Controlled generation window -keep edits focused
Replacement ranges are constrained to practical editing windows, keeping the task focused and predictable. The draft panel summarizes duration, lyric lines, style tags, and merge readiness before generation.
