"Heart of a Hero" is the closing theme song of the Disney Junior animated series, The Rocketeer. The full song is first heard in the pilot episode "First Flight" when Kit suits up and flies to rescue her dad during an airshow.
Lyrics
Follow your heart
It was meant to fly
Follow your heart
It leads to the sky
Feel the joy inside when you
Are doing what you were born to do
The heart of a hero
Will see you through
The heart of a hero
Beats inside of you
