There are a great number of songs that are written about the moon (moonlight, moonshine,etc, etc.).I'm not sure that the star in our solar system is getting equal billing.Therefore, let's talk about the sun as mentioned in songs.To begin, I would choose as a first example a song by John Denver, http://www.youtube.com/watch?v=eivZd4j5MBs, "Sunshine on my Shoulder".
