This week would have to be 'Mein Teil' from Rammstein:
from wikipedia:
"Mein Teil" (German: "My part") is the first single by the German industrial metal band Rammstein from their fourth album Reise, Reise. The song is inspired by the case of Armin Meiwes and Bernd Jürgen Armando Brandes. In March 2001, in Rotenburg an der Fulda,
the two men aged in their 40s met each other, cut off and cooked
Brandes' penis and consumed it together. Afterwards, Meiwes killed
Brandes—with Brandes' consent—and ate his remains. As a result, Meiwes
was sentenced to eight-and-a-half years in jail for manslaughter,
but was later charged with murder and sentenced to life imprisonment. A
prominent phrase in the song is "Denn du bist was du isst und ihr wisst
was es ist" ("Because you are what you eat and you (plural) know what
it is").
According to Rammstein's bassist Oliver Riedel, the song came about after "one of our members brought a newspaper to rehearsal and it had a story about the cannibal guy in it. We were fascinated, shocked and amused at the same time." Vocalist Till Lindemann stated, "It's so sick that it becomes fascinating and there just has to be a song about it".
