I guess someone has to include 'viva la vida'...and as no has yet...it has to be me! http://www.last.fm/music/Coldplay/_/Viva+La+Vida
There are several layers of meaning to the song I am sure, and one will appeal to almost everyone. Perhaps the most obvious interpretation is that of 'love lost'...hence, 'when I ruled the world'...
The chess reference is at the end...
