Kraftwerk "Radio-Activity".
For some reason, I wanted to hear the songs "Radioland" and "The Voice of Energy".
Although "The Voice of Energy" is in German, I found a translation of the lyrics:
This is the Voice of Energy
I am a giant electrical generator
I supply you with light and power
And I enable you to receive Speech,
Music and Image through the Ether
I am your servant and lord at the same time
Therefore guard me well
Me, the genius of Energy
