This song was from the movie The Chronicles of Narnia: Prince Caspian. I think it was sung nearing the end of the show. Am rather hook to it right now =)

The Call
Regina Spektor

It started out as a feeling
Which then grew into a hope
Which then turned into a quiet thought
Which then turned into a quiet word

And then that word grew louder and louder
'Til it was a battle cry

I'll come back
When you call me
No need to say goodbye

Just because everything's changing
Doesn't mean it's never
Been this way before

All you can do is try to know
Who your friends are
As you head off to the war

Pick a star on the dark horizon
And follow the light

You'll come back
When it's over
No need to say good bye

You'll come back
When it's over
No need to say good bye

Now we're back to the beginning
It's just a feeling and no one knows yet
But just because they can't feel it too
Doesn't mean that you have to forget

Let your memories grow stronger and stronger
'Til they're before your eyes

You'll come back
When they call you
No need to say good bye

You'll come back
When they call you
No need to say good bye
