I have a problem in general with the argument that every poem, or painting, or film, means something different to each viewer.
Language is, first of all, communication.
Most of us intutively sense that the better the language, the more accurate and articulate we are, the better we are able to share our thoughts and ideas. In my view, too many lyricists nowadays resort to obscurity in order to camoflage the fact that they are not sure of what they are saying, and don't want to be held accountable for it. The more you listen to his songs, the more you discover specific meanings. You could say that some people might think of Babel, and that would be good. It makes it a rich, memorable image, because it all hangs together, resonates with each other, builds towards an epiphany.
