I guess lyrically they're similar because they're talking about escaping the kind of misery that likes company. 'The Last One Alive ' for me is very simple. It's just about alienation really that causes anger.
When I was younger I was terrified to express anger because it would often kick-start a horrible reaction in the men in my life. So I bit my tongue. I was left to painstakingly deal with the aftermath of my avoidance later in life in therapy or through the lyrics of my songs.
Music should probably provide answers in terms of lyrical content and giving people a sense of togetherness and oneness as opposed to being alone in their thoughts and dilemmas or regrets or happiness or whatever.
I try to write lyrics so that they won't age which sort of leaves you with the big subjects like death and love and sex and violence.
