Oh boy, that last one. You might be sorry what you asked for! I probably worry more than I should. I think that is likely a common one for a lot of people. There are a few songs that make me tear up a little. Golden Slumbers by the Beatles for sure. Only recently though because it was playing when we were driving our dog to the vet to say goodbye to her. Also, Best Thing that Ever Happened To Me by Gladys Knight because it makes me think of my wife.
