Hey guys I am looking for songs that have emphasize on goverment control, much like Greed Day's songs...?

I need songs that for instance describe how the world is being controlled by an outer force, a very strong influential force, such as a dictator. Like Metallica's Master of Puppets is a great example. So if anyone is aware of any songs like this that would be great. I fyou are wondering why I am looking for these songs it is because I am trying to find songs that relate to the novel 1984 by Orwell, if you are aware of that story.
