Music Search Lockscreen Widget History

I have a Nexus 4 running 4.4 (Kitkat) and I use the Music Search widget while listening to the radio on my car. I have discovered the name of that song or artist I wanted to know many times, but now I realize I can't seem to find my music "search history." Can anyone point me in the right direction? Is this in the (Play) Music App or Settings? I've looked everywhere! Reading thru the Google Help led me no where...  UPDATE: I answered my own question and cleared up the issue, giving credit where due. BTW the picture above was from illustration purposes only, and apparently from a device that has the Sound Search widget history disabled. Sound Search History is not available is some countries.
