This guardian angel

Shining eyes, a heavanly voice,
said: I like your songs. I like your kind.
I am your shield and I'll make you famous!
And daydreams made the fool so blind

And then this...
This guardian angel has bought a cloud of gold
this guardian angel bags all our crop alone
this guardian angel, I guess has sold our soul

Excuse me, Sir, here's my termination,
I'm famished and my purse is empty
he laughed at me: you will go nowhere.
you've signed with your blood, you'll stay forever with me!

And then this...
This guardian angel has bought a cloud of gold
this guardian angel bags all our crop alone
this guardian angel, I guess has sold our soul
