# AI Song Extender

> Kenerate's AI song extender makes a song longer by continuing it — pick a song in your Music Studio library, write the lyrics for the new part and choose where the continuation starts, and Extend (Mureka V8) generates the rest in the same style and voice. In our tests a 31-second clip became 1:20 and 2:45 full songs. Extend works on songs you made in the studio; a new account gets 25 free credits.

## In depth

### Why extend instead of regenerating
Regenerating a longer song gives you a different song. Extending keeps what you already like — the voice, the melody, the hook — and adds to it. That's why short clip engines like Ken Music 1 pair well with Extend: find a hook you love in 30 seconds, then build the full song around it.

### Writing lyrics for the extension
The extension sings exactly what you give it, so:
- Match the meter — similar syllable counts per line as the original.
- Continue the story — verse 2 should move forward, not restart.
- Echo the hook — reuse the chorus line from the original.
- Use tags — [Verse 2] and [Chorus] tell it which part is which.
