For Valentine's...some classic German chanson for you. Sorry, some of the images are strange, but it's for the music.
Hildegard Knef, "Für mich soll's rote Rosen regnen," famous for her deep, smoky voice. If you want more, Eins und eins, das macht zwei, or In dieser Stadt and Heimweh nach dem Kurfürstendamm (she was a Berlinerin).
Zarah Leander, "Nur nicht aus Liebe weinen" (Swedish actress/singer, who worked/lived in Germany many years. Controversially kept making films during the Nazi period, but that's another topic)
And the amazing Marlene Dietrich, from the film Der blaue Engel "Ich bin von Kopf bis Fuß..." (Also became famous in the English version, "Falling in Love Again.")
