1. "Square One" - X & Y
2. "What If" - X & Y
Another song included in X & Y (seriously, one of the greatest), this song not only includes the beautiful melodies of the lovely Chris Martin, but also acknowledges the fact that sometimes life doesn't go as we want and that it's okay to be caught in the eye of the storm. An excellent song to listen to when you're having just one of those days.
3. Us Against the World - Mylo Xyloto
4. Gravity - X & Y
This song that starts as a soft ballad does an amazing job transitioning it's music through the flow of lyrics that makes you consider if a piece of your heart wrote it for your significant other.
