"Jeanny" by Falco. One of the biggest and earliest REEEEEEEE moments in German music landscape, back in the 1980s.
The song is about a guy who has abducted a girl, and he's singing to her, describing the moments before he took her, how she wanted it too. Then there's a TV newsflash where it's revealed that there has been a series of disappearances, and that now there's another, 15 year old girl who went missing. Then the kidnapper/killer is singing to her that Police is coming, but they won't find her because she is with him.
Chilling song by a mad genius.
