"Beasts of England" is a representation of the many revolutionary songs that have existed throughout history. By limiting a philosophy to an easily-remembered song, it is possible to seed even unpopular ideas in the mind with little effort. Since many of the animals lack the fully-formed cognition that would allow them to truly understand Old Major's ideas, the song acts as a popular concept and something that everyone can participate in. The animals take it up first as revolutionary, and then as a sort of national anthem. Eventually, Napoleon bans the song because of its implicit revolutionary ideals; he does not want the animals thinking about their revolution over the human, because they might apply the same ideas to his own rule.
