Kraftwerk frontman RALF HUTTER refuses to put on music at home, because he prefers to listen to the imaginary tunes in his head.

The AUTOBAHN star insists on silence in order to fuel his creativity, using only the elements in his immediate environment to inspire him.

He says, "Sometimes I put things on or flick through the stations. But not so much.

"I try to fantasise music, to imagine what new music might be like, and for that you need silence, or interesting sounds - the environment, or different languages, different people, like from New York The Ramones, or from Detroit the MC5 and THE STOOGES' sound."
