Well I knew it was a metaphor for the hollywood thing but I always think of it like a twilight zone thing, I mean, any way you look at it it still makes some sort of sense, at the very least you could say it's a very strange story.
I don't, I like a lot of songs that don't make sense, but for a song to be truly great it's got to have great music and great lyrics.
Also, how does Hotel California not make sense? It has a whole plot thing going on.
