Thank you, Jill. I'm glad I'm not in charge of choosing one song. I don't think I could ever make up my mind. But, in the spirit of this article, I guess I would have to pick the Dine Night Chant which includes this prayer:
May it be beautiful before me.
May it be beautiful behind me.
May it be beautiful below me. 
May it be beautiful above me.
May it be beautiful all around me.
In beauty it is finished."
