Propaganda is the 18th track of the Battle Tendency (Musik) Anime Soundtrack. The song was used in the second arc of the series, Part II: Battle Tendency as the theme of the character, Rudol von Stroheim.
The lyrics of the song are pulled from chapters of Thus Spoke Zarathustra: A Book for All and None, a philosophical novel by German philosopher, Friedrich Nietzsche, inventor of the Übermensch.
The concept of the Übermensch coincides with the ideology of the Nazi's in the series, and is mentioned by Stroheim when revealing his gatling gun in Episode 19. Even though Nietzsche himself was a fierce opponent of what later became the ideology of the Nazi party, some of them were moved by his work without being "converted" (or used the severely manipulative version of his work published by his sister), as it was probably the case of Stroheim.
The given English translation of the lyrics here are taken from Thomas Common's translation of said book.
