I speak some German and have a fair working knowledge of the language. I have also heard songs sung in German and they sound pretty cool in their own right, maybe not quite as sexy as French, but stil they sound good. I like to hear some Christmas songs and church hymns in German. Silent Night is especially nice in German. Of course, being able to understand the words makes it better. Here is the first verse of Silent Night in German:
Stille Nacht, heilige Nacht,
Alles schläft; einsam wacht
Nur das traute hochheilige Paar.
Holder Knabe im lockigen Haar,
Schlaf in himmlischer Ruh!
Schlaf in himmlischer Ruh!
