In honor of the 30th anniversary...if you don't remember this, well, here it is:
A translation of the chorus for the less German-proficient reader:
Ich liebe dich nicht, du liebst mich nicht
"I do not love you, you do not love me," or something like that.
Note the utter simplicity of the arrangement, the clever internal rhyme...there is more here than the surface. Or perhaps less. Life is still a Mystery.
