My favorite song is Kraftwerk's Autobahn, but the lyrics aren't the reason why, it's the song structure and the synthesizer performance that I like.

Still, my favorite lyric from it is probably:

Wir fahr'n, fahr'n, fahr'n auf der Autobahn
Wir fahr'n, fahr'n, fahr'n auf der Autobahn
Jetzt schalten wir das Radio an
Aus dem Lautsprecher klingt es dann
Wir fahr'n, fahr'n, fahr'n auf der Autobahn

(translation: We're driving on the Autobahn, we're driving on the autobahn. Now we turn on the radio and from the speaker it says: we're driving on the Autobahn!)

There's a story that when Kraftwerk were touring in the US for the first time, they randomly turned on the radio in their rental car and immediately heard the line in their song about turning on the radio
