This song is sung by Garth Brooks (yes, I know it is country but it is really quite beautiful so give it a chance) and when I heard it my first thought was of Cloud singing this song. What do you think?

Here is a muisc video of this song! The song is from a movie called Frequency. It is really beautiful so please watch it!

When You Come Back To Me Again

There's a ship out, on the ocean
At the mercy of the sea
It's been tossed about, lost and broken
Wandering aimlessly
And God somehow you know that ship is me

'Cause there's a lighthouse, in the harbor
Shining faithfully
Pouring its light out, across the water
For this sinking soul to see
That someone out there still believes in me

Chorus
On a prayer, in a song
I hear your voice and it keeps me hanging on
Raining down, against the wind
I'm reaching out 'til we reach the circle's end
When you come back to me again

There's a moment we all come to
In our own time and our own space
Where all that we've done, we can undo
If our heart's in the right place

Chorus
On a prayer, in a song
I hear your voice and it keeps me hanging on
Raining down, against the wind
I'm reaching out 'til we reach the circle's end
When you come back to me again

And again I see my yesterday's in front of me
Unfolding like a mystery
You're changing all that is and used to be

On a prayer, in a song
I hear your voice and it keeps me hanging on
Raining down, against the wind
I'm reaching out 'til we reach the circle's end
When you come back to me again

When you come back to me again
