Tracy Chapman's "Remember the Tinman". 

  "There are locks on the door and chains stretched
across all the entries to the inside
There's a gate and a fence and bars to
protect from g*d knows what lurks outside
Who stole your heart?  Who took it away
knowing that without you can't live?
Who took away the part, so essential to the whole? 
What robber, what thief?
Left you a hollow body, skin and bone.
What robber, what thief.  
"Who stole your heart, the smile from your face,
the innocence the light from your eyes
Who stole your heart, or did you give it away.
And if so then when and why?
Who tookd away the part, so essential to the hole.
Left you a hollow body? Skin and bone.
What robber, what thief?
Now all sentiment is gone.  
Now you have no trust in no one.
"Who stole your heart? 
Did you know but forget the method and moment in time
Was it a trickster using mirrors and sleight of hand  
A strong elixir, Or a potion that you drank?

"Who hurt your heart bruised it in a place
That no one and nothing can heal
You've gone to wizards, princes and magic men.  
You've gone to witches, The good the bad the indifferent.  
But still all sentiment is gone, but still you have no trust in no one

   "If you can tear down the walls, throw your
armor away, remove allroadblocks barricades
If you can forget there are bandits and drgons to slay.
And don't forget that you defend an empty space.  
And remember the tinman, found that he had what he thought he lacked
Remember the tinman. Go find your heart, and take it back.  
"Who stole your heart, Maybe no one can say,
One day you will find it, I pray."
