A few that people came up with in the 2006 list that are favorites of mine:
"What I Did for Love" (A Chorus Line)
"Yours, Yours, Yours" (1776)
"Send in the Clowns" (A Little Night Music)
"All I Ask of You" (The Phantom of the Opera)
"The Party's Over" (Bells Are Ringing)
And from the 2005 list:
"In a Most Unusual Way" (Nine)
"Fallin'" (They're Playing Our Song)
I will admit that I like "What I Did for Love" so much that I have already told all the family that when my time comes (in the distant fture), I want it sung at my memorial service.
"Gone,
Love is never gone.
As we travel on,
Love's hat we'll remember."
