Mercury

I went through too many people
I went thru heaven and hell
I went from Rome to Baghdad
Too many stories to tell 

I lived thru too many aeons
I've risen up and I fell the fall
I have been there and I have done that
I've see it all and all 

My time is running like water
Deeper I dive and deeper
Last of nine lives of the cat
I saved my soul for the reaper 

What do you mean by that
Mercy is all you get
Do what you won't regret
Freedom's your self-respect
What do you mean by that
