The blues are full of great references to money. Junior Wells used to sing:

People come and ask me, how does a poor man do,
Sews patches on his clothes, stuffs newspapers down in his shoes.

And Brownie McGhee's "Pawn Shop Blues":

I asked the pawn shop man, what are those three balls doin' on the wall,
He said I'll bet you two to one buddy, you don't get your stuff outta here at all.

Pete Seeger used to sing:

Times are gettin' hard boys, money's gettin' scarce,
Times don't get no better boys, I'm bound to leave this place,
I'll take my true love by the hand, and lead her through the town,
Sayin' goodbye to every one, goodbye to everyone.

Hoyt Axton: "Greenback Dollar."

Woody Guthrie: "Do Re Mi."

Eleven Cent Cotton and Forty Cent Meat

Too Old To Work (And Too Young To Die)

Pay Day At Coal Creek

Money Honey

Rip It Up ["I'm a fool about my money, don't try to save..."]

Ten Cents a Dance

Boy this could become a long thread.
