On suggestions please

Wanna help?? For my Sociology class, we're beginning a project for which I have to choose just one song that is going to be "my song." This song is supposed to tie significantly to my life and who I am. I have a few in mind, but wouldn't mind suggestions. If you think of some thing that would be good for me to use, let me know. Bonus: for a few days, I get to listen to my MP3 player in class...bet you're jealous...
