You Me :

stop commenting on my wall

I used to rule the world
Seas would rise when I gave the word
Now in the morning, I sleep alone
Sweep the streets I used to own
I used to roll the dice
Feel the fear in my enemy's eyes
Listen as the crowd would sing
Now the old king is dead, long live the king
One minute, I held the key
Next the walls were closed on me
And I discovered that my castles stand
Upon pillars of salt and pillars of sand
