I feel a good deal of this song is influenced by a Dylan Thomas poem called "In My Craft or Sullen Art"...
In my craft or sullen art
Exercised in the still night
When only the moon rages
And the lovers lie abed
With all their griefs in their arms,
I labour by singing light
Not for ambition or bread
Or the strut and trade of charms
On the ivory stages
But for the common wages
Of their most secret heart.
Not for the proud man apart
From the raging moon I write
On these spindrift pages
Not for the towering dead
With their nightingales and psalms
But for the lovers, their arms
Round the griefs of the ages,
Who pay no praise or wages
Nor heed my craft or art.
If someone wants, I can elaborate.
I can start you off with:
Dylan says he "labors by singing light"
Hunter says "what if my words did glow with the gold of sunshine"
Dylan says "not for ambition or bread, or the strut and trade of charms"
Hunter says "Its a hand-me-down, thoughts are broken... don't know, don't really care"
The title of Dylan's poem is key. This is the distinction he is making. Some people preceive his poetry as a sullen art, others as his craft. And I would say its not the craft like a trade (blacksmithing, etc.), but the craft like a traveling vessel (boat, etc.).
