I like the classic, "Nobody Knows You When You're Down and Out", as performed by various artists from Bessie Smith to Eric Clapton.

"if I ever get my hands on a dollar again,
I'm gonna squeeze it and squeeze it 'til the old eagle grins..."

I also like the more obscure "Money Talks" by Jason and the Scorchers.

"if money talks, why don't it speak to me,
I need the conversation it's plain to see..."
