I love, love, love this tune.  Whenever I recorded Cold Case, I would keep rewinding the beginning, just to hear the opening theme tune over and over.  I had no idea where this tune came from, and was in a roundabout way lead to it through Pandora.  I am so glad I found it and am able to listen to it whenever I want to now.  On a side note, I wish Cold Case had not gotten cancelled when it did.  It was one of my favorite shows to watch, theme tune aside.
