Kom, Susser Tod. Sounds happy, but listen to the lyrics. (And of course the title means "Come, Sweet Death"...)
Another great one is DEVO's "Beautiful World". The weird thing is that this was even used for a Target commercial, but if you listen to the lyrics it's...pretty amazing.
It's a beautiful world we live in,
A sweet romantic place,
Beautiful people everywhere,
The way they show they care
Makes me want to say,
It's a beautiful world, it's a beautiful world, it's a beautiful world
For you...for you...for you...
IT'S NOT FOR ME
