I like Enter Shikari. I like their music. Though I can't be arsed with their political anarchy nonsense. All the anti-capitalist shit is boring enough from people without any real influence in the world. If they want to make a change, stop playing music and become politicians.
Music expresses people's voices/opinions, of course they're going to include the government into their lyrics if they dislike it; in fact, this is a great way to get their fans to become more voiced about the pathetic government these days. If anything you could call it musical politicians.
