Whenever my head gets clogged up with such deep thoughts, I just start playing Gene Chandler's "Duke of Earl" in my head; clears the cobwebs out right away.
I like old songs too, but I'm more into this kind of songs: " erba di casa mia" , like "grass of my home" is like a nostalgic memory of the spring time of life. http://www.youtube.com/watch?v=L_QliRxQ6Mc
