Interesting possibilities, David.
I found 'Reporting Back' to Love in the third Line of each Verse helped me tie it all together.
The coherence of the 'money' theme was not easy to remember because of the 'Over-Repetition' of relevant concepts, relevant to money, so throwing a little 'Love' in with 'Money' seemed to help me think through it.
That concept of 'Reporting Back' is something I noticed in Dylan's Songs, like "Tangled Up In Blue". It's a long Composition, more Poetic than Lyrical, but Reporting Back to that Title Line, even with its vague meaning, ties the whole together.
In "It's Just Money" the third Line, not the Title, seemed to have that 'cohering' benefit for me, keeping me aware of where I was in the 'Storyline' with so many 'money' references.
A Song must have 'Enough' Repetition to supply Structure listeners can relate to, and 'Enough' Change to keep listeners interested.
That Judgment Call applies to Melody and to Lyric. How much is 'Enough', or 'Not Enough', or 'Too Much'. The Songwriter's Judgment Call. Listeners will make their own Judgment Call, so the Songwriter can influence theirs by exercising some 'judgment' of his own.
There is 'inspiration' and then there can be 'crafting'. Inspiration is ad lib, whatever comes out of the instrument and whatever Lyric comes out of the brain through the mouth. Keeping or Sweeping is part of that Judgment Call at the time of creation. A more scrutinizing Judgment Call, a post-creation 'assessment' is the crafting.
"It's Just Money" is fun, with Component parts that keep it interesting, for me. The Bridge is brief, only long 'Enough' to serve that function of breaking the Repetition, renewing listener interest, and then back to the Verse Melody, the Chorus Refrain, and out.

There will always be another song to be written. Someone will write it. Why not you? www.garyeandrews.com
