The meaning of this song is much more obvious when you realize the references that ben is making to the Bible. "If the sun sets you free then you'll be free indeed", is actually a reference to john 8:36, when Jesus says, "if the SON sets you free, then you will be free indeed" -the Son being Jesus Christ, rather than sun. So, basically, ben is singing about a dead chick.
