Too hard! I love music, so I get three!
First: Run by Collective Soul
This was in Varsity Blues my senior year of high school and for some reason it is one of the only things that can calm me down.
Second: I Can Only Imagine by MercyMe
My favorite Christian song. I have a lot of reasons for this, but imagine is my favorite word, so it seemed pretty natural, plus a lot of things have happened during this song (ie. My junior year of college)
Third: Imaging by John Lennon
I just love the message of this song, the idea that if the world could just get along it would be a better place for all of us. Plus again, imagine is my favorite word.
