Ya the chorus is wrong. But thanks for adding lyrics anyways =D so. In my opinion, I think this song is about young people born in countries that have war in them.: "As we walk among these shadows, in these streets, these fields of battle". In the song, it clearly explains that they fight against all they have ever known "walk alone against all we've ever known" --- and also, another example is that they say that all we have ever wanted was a place to call home, but couldn't since its never safe and we always have to run away from it "All we've ever really wanted was a place to call our home"--
Anyways. That's what I think. :)
