in "money", when you say "i said it 3 or 4 songs ago", are you actually referencing a previous song or is it a meaningless lyric?
it's evoking multiple meanings. "hello, it's a tuesday show, cuz wednesday seems so long ago. i said it 3 or 4 songs ago. IT'S TIME FOR THE SHOW". Whether i'm referring to saying 'hello', or mentioning the 'tuesday show' or mentioning 'tuesday' then 'wednesday' in succession like that in a song, or simply declaring "it's time for the show", all of those are things i've either said before, or put in a song before. So that's 5 things at once that it means, and the 3-or-4-songs-ago is just an estimation, because all those things happened varying degrees of time ago. In the cases of things being put into songs, it's usually more than 4 songs ago, giving a whimsical over-casual sense to the estimate, but then the incidents where i've just said them (such as talked about them here on this page, or in notes, or otherwise in life) expressed things such as the desire to have a regularly occuring show, my preference for Tuesday for such an event, in those cases, the "3 or 4 songs ago" is just a way of mentioning time. indeed, when we say "3 or 4 days ago", we say "days" because days are something that happen so often and so regularly that they can be used to measure time. so it can also be seen that i'm sort of wistfully refering to 'songs' as something so regular and frequent that they ought to be used to measure time, even if just in casual estimation. most of all, all these meanings likely converge on "it's time for the show", which is indeed something that came out in an improv, in a similarly decisive and succinct way. these are the various meanings of that line, in context of the lines surrounding it
