If a song cuts off too early, it can be fixed. No need to regenerate the whole thing.

Songer will generate a proper ending from that point.
Note
A few things to know about how extensions work:
The goal is a smooth, complete-sounding ending
Two alternative endings are generated each time
Extended tracks are marked with an Extension tag
You can find them quickly:
Desktop: Ctrl + F and search for “Extension”
Mobile: Use your browser's Find feature
If the ending still isn’t right, you can use Extend again and refine it further
Sometimes one pass is enough. Sometimes it takes two. That’s normal.
