Castle Walls (feat. Christina Aguilera)

Everyone thinks that I have it all
But it's so empty living behind these castle walls
These castle walls
If I should stumble, if I should fall
Will anyone hear me screaming behind these castle walls
There's no one here at all
Behind these castle walls

Nobody knows I'm all alone 
living in this castle made of stone
They say that money is freedom but I feel trapped inside it all
And while I sit so high up on a throne
I wonder how I can feel this low, 
on top of the world it's beautiful
But there's no place to fall
