Chrysanthemum, I kind of agree with "Not For The Life of Me," although it may have been more appropriate a few years ago. My parents and I saw Millie after I attended a pre-college program in NYC (at the school I go to now), and after she sang the line "Manhattan, I prepared for you," my dad leaned over and whispered, "She sounds like you." "Not For The Life of Me" and "Only in New York" will always have a lot of sentimental value.
I'm not sure what song best fits my life right now, but in a year and a half it will be "I Wish I Could Go Back to College" from Avenue Q.
