If you have heard them... surely you must admit that they 'feel' different? If you can't then..... oh well..... never mind.
I will not admit that they feel different because I do not think that they do!
They are very different indeed. When Ralf is singing in German, he gets it "right" so to speak. It's quite obvious since he's a German. When he's singing in English, it gets kind of corny I think. Pronunciation isn't the best, and the melody of his voice is all different, and not as polished as his German lyrics. For some reason, whenever Ralf is singing in English, he sounds more "upbeat" and a bit like a parody of himself, which to me makes the music sillier than it is. Only when he sings in his native language you get the real Kraftwerk-sound; the colder and more monotonous feel that works so well. I think the best example is the TEE album, which in my opinion is a LOT better in German. Just by having the German lyrics, the album changes "tone" from a disco platter to something quite serious - at least in my ears. The monotonous beats in TEE works so much better with the colder and more industrial feel you get with Trans...Europa...Express... :) "Trans Europe Express" just doesn't work for me, even though the difference should be very slight, but it isn't. Call me crazy, but if you haven't heard KW in German, you're not listening!!
