It's like those Saturday morning cartoon villians who talk about being evil and doing things in the name of darkness and such but these guys seem way more upbeat about it.
The musical style is an exact duplicate of "Schoolhouse rock" which was an educational video popular during the early 80s. It was also required that childrens programming contain "educational content", which is why schoolhouse rock was created. GI Joe and Transformers contained educational messages at the end for the exact same reason. The legistlation AFAICT is still in place, but enforcement is obviously pretty lax.
The reason Psyop chose schoolhouse rock was because it triggers a "I am learning something" feeling in viewers, tricking them into internalizing the Psyop message. The name "psyop anthem" is no accident either; anthem being defined here:

Note that PPP itself is an acronym for Philosophy Politics and Psychology (CIA terminology). I am not trying to infer some kind of conspiracy here, since Psyop are refreshingly open about their cynical exploitation of the human psyche
