The song “Let it Go” from the Walt Disney movie Frozen has enjoyed popularity on a worldwide scale. Yes, the songstress Idina Menzel’s voice is powerful, and the song does have a catchy tune. And, yes it is from one of the most beloved movies of all times (Frozen is the fifth highest grossing movie and the No. 1 highest grossing animated movie ever) but I think what people of all ages love about the song is that you can belt out the words “let it go” over and over again. It just feels so good whether you’re in the shower, driving down the road or at work. It’s a song with built-in self-defense. For instance, you’re driving down the road and a crazy driver cuts you off, there’s no need to get mad. You just sing out “let it go, let it go, let it go, let it go!” It has an instant calming effect with a much better prophecy than “let it snow, let it snow, let it snow!”
