I'm sorry if my tone puts you off, I'm just angry because I'm lonely all the time and will be found dead on the phone, dragged down by the stone one day (am I doing it right guys?)
Feel free to discontinue this conversation but I still want to ask, what does "understanding a metaphor" mean? Do you understand it on your own upon reading the lyrics? Or do you have to read a wiki or a blog/discuss it with others, and then you understand and accept it? If the latter, doesn't that contradict the concept of understanding? Doesn't it mean the lyrics are inexplicable and thus should be deemed meaningless?
Are we talking about a big yet finite number of literary metaphors that you learn as you go forward in life, or does concept music have an infinite amount of metaphors than any songwriter with a pen can conjure up? If the latter is the case, because art, then how am I supposed to understand what he intended?
If it's subjective, then why does it seem that people who claim they understand the concept lyrics, usually agree on what that 'album was about'?
I don't understand why you're having such a problem with the fact that people draw their own meanings from songs, but when they discuss an album they like, can come to an agreement on an overall meaning or theme.
The Wall had a movie made about it, so obviously there was a story structure within the piece of music.
