Regarding the title of this thread, I ought to let you know that although the leader of Kraftwerk, Ralf Hutter, was normally very laid back, one way to set him off in an uncontrollable rage was to mention the words "Kraftwerk" and "Krautrock" in the same sentence.
It never failed.
He absolutely hated the term "Krautrock" and he didn't particularly like any other kind of rock music either!
