I'M German and actaully I hate German Muzik XD
But though there are a few songs in German I like. For example I liked one of Herbert Grönemeyers ( anda know him?) first songs: "Mensch" - he makes good textes. But .. he can't sing. XD Though he is like one of the most famous german singers O.o
Then I think "Allein Allein" from Polarkreis 18 is a very nice song (was also a big hit a few years ago) - But I don't know if it really counts till most of the text is except the chorus is English XD
And then I found a song on the Internet, I really loved the text of. It is called "Meine Welt" sejak Peter Heppner. I'll try finding that official musicvideo - cuz it shows what he's Singing of. He's Singing that in his Fantasi he can make everything happen and that he doesn't care if it's not really realizable. (translated one part: "I draw money that nobody counts, And then I draw a war in that nobody ever dies" - just short) - Besides, on the side of the Muzik (melody) it's also a good song I think.
I couldn't embed the link, so here it is like that:
