If you just believe ...

Believe in what your heart is saying,
Hear the melody that's playing.
There's no time to waste,
There so much to celebrate.
Believe in what you feel inside,
Give your dreams the wings to fly.
You have everything you need, if you just believe.

Believe, letra e música de Glenn Ballard e  Alan Silvestri. Interpretada por Josh Groban. Banda sonora do filme Polar Express de Robert Zemeckis, 2004.
