Once Upon A Time swan song

Emma: Once I lived in darkness,
Out there on my own
Left to brave the world alone
Everything seemed hopeless
No chance to break free
Couldn't hear the song inside of me
Once upon a time
A song inspired them, be brave
They gave me up because my fate
Was as the one who'd save
The world from your dark magic
And the wicked things you do
They placed a song inside my heart
More powerful than you
Henry: mom, keep going, you can do it!
Emma: All the years of running
No, not anymore
I know what I'm living for
I'm no longer searching
Turns out all along,
The answer was inside me
With a song
