Someone once said that "The Waste Land" was a scum of poetry floating on a sea of footnotes. That resonated with me, because that's kind of what I was doing lyrically for a while. I was being very referential in a way. I would drop in these little phrases or ideas that were sort of portholes into a whole bigger realm of thought or whatever, that would work within the song, but that you could also poke through into a bigger discussion.
