Self Esteem Playlist

I was reading on Cafemom about a Self Esteem playlist that someone created.  I started thinking that it's a great idea!  I have playlists for when I'm having a bad day, when I'm sad or angry, but I can always use more music!  We all can, right?
So Now I'm thinking about what songs would be on my playlist to boost me up and what would my number one song be?
This might take me a bit to figure out and gather up all the music, so until then - tell me what your #1 song would be?
