I didn't feel like I could choose just "any" song.  It had to be a song that had a bit deeper meaning to me.  It had to hold a memory (which most songs do) that was very dear to my heart!  Also it had to be a good song, meaning basically a song I enjoy that I can listen to over and over again without getting sick of it.

Of course I will get new favorites as time goes on, but this list is a good list for me to always refer back to :)
