Electric Eye Judas Priest

The Three Laws, quoted from the "Handbook of Robotics, 56th Edition, 2058 A.D.", are:
First Law
A robot may not injure a human being or, through inaction, allow a human being to come to harm.
Second Law
A robot must obey the orders given it by human beings except where such orders would conflict with the First Law.
Third Law
A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.
In later fiction where robots had taken responsibility for government of whole planets and human civilizations, Asimov also added a fourth, or zeroth law, to precede the others:

Zeroth Law
A robot may not harm humanity, or, by inaction, allow humanity to come to harm.
"Electric Eye" is the second song on English heavy metal band Judas Priest’s 1982 album Screaming for Vengeance. It has become a staple at concerts, usually played as the first song. AllMusic critic Steve Huey called the song a classic.

Musically, the song is in the key of E minor, and its guitar solo is played by Glenn Tipton.

"Electric Eye" is an allusion to the book Nineteen Eighty-Four by George Orwell, in the use of the name of the pseudo-omniscient camera that watches over the community at all times. In this dystopia, the form of government, Ingsoc (Newspeak for English Socialism), is utterly totalitarian, and if citizens are caught rebelling in any manner, they "disappear". In the song by Judas Priest, however, the cameras are updated to take the form of a powerful satellite, that is "elected," to take "pictures that can prove," and "keep the country clean". Thus, the song has been called "prescient" for its depiction of a modern surveillance state, operating within the context of an ostensibly democratic nation.

Up here in space
I'm looking down on you
My laser's trace
Everything you do

You think you've private lives
Think nothing of the kind
There is no true escape
I'm watching all the time

I'm made of metal
My circuits gleam
I am perpetual
I keep the country clean

I'm elected, electric spy
I'm protected, electric eye

Always in focus
You can't feel my stare
I zoom into you
But you don't know I'm there

I take a pride in probing
All your secret moves
My tearless retina
Takes pictures that can prove

I'm made of metal
My circuits gleam
I am perpetual
I keep the country clean

I'm elected, electric spy
I'm protected, electric eye

Electric eye
In the sky
They feel the stare
So always there

There's nothing you can do about it
Develop and expose
I feed upon your every thought
And so my power grows

I'm made of metal
My circuits gleam
I am perpetual
I keep the country clean

I'm elected, electric spy
I'm protected, electric eye
I'm elected, electric spy
I'm elected

Protective, detective
Electric eye
