This is from the Soundtrack of "Metropolis"
The 1984 Giorgio Moroder version
Circles of the human chain
Turning for the wheels of gain
A system with a power of it’s own
To draw blood from a stone
Every hour like the last
Tomorrow like today just passed
Bearing down the upon the flesh and bone
To draw blood from a stone
Cold machines that never stop
Even if a man should drop
Mercy never let’s her face be shown
They draw blood from a stone
