There's a story about a girl who saves a village with her singing

Everyone in her village is disappearing.
She starts to sing
and discovers it stops the disappearing,
so she keeps singing.

Soon she knocks on all the people’s doors to sing to them,
and they reappear
and then there are more
until the town is alive again.

I dream one night it’s true
and I'm her.

But my family is gone and they won't come back
no matter how much I sing.
