Nadčlověk is translated as Superman by every dictionary but I'm unsure if that's what you call it in US (because I imagine the comics Superman tbh). Nadčlověk is the human of the new clean race that Hitler/fascists tried to create (as pictured on the cover I guess). The blond aryan with blue eyes, not malformed genetically and shit. What do you call that?
The title says then:
Radical Atheism - To The Creators of ****.
The titles of songs then say that creating this superrace is humanly alright and that people should never more support the "unfitting" etc.

I can't hear every word in the songs but there are also references to judes going to death and shit.
I have to agree though that it fits into the music.
