What song defines your personality?

Curiosity made me post this: What song out there defines who you are? Whether it be who you think you are to others, what others think of you, or something along those lines. For me, In the real world, it would be this song: http://www.youtube.com/watch?v=rNHSbikujn4 (Stranger) Online it would be this song: http://www.youtube.com/watch?v=YMCmgjWSFeA&list=PLMPSiq5MeE94m5UuweDNoofO_cQ2gbGk7 (Absolutely Spoiled)

I don't think there's a song that can completely define me, but there are some songs that I start thinking about between emotions.
