DMB (not sure if it is the "most" but it surely ranks)
Standing here
The old man said to me
"Long before these crowded streets
Here stood my dreaming tree"
Below it he would sit
For hours at a time
Now, progress takes away
What forever took to find
Written by Guy Clark, performed by Lyle Lovett (this one also is at or near the top of my list)
Here's a book of poems I got
From a girl I used to know
I guess I read it front to back
Fifty times or so
It's all about the good life
And stayin' at ease with the world
It's funny how I love that book
And I never loved that girl
