There are times when I simply need music in my life. I switch on Google Play Music and access my library to just drift away. As songs drift by using random play, my mind takes me back to the places and times in my life where I first heard the song or to a point in my life when the song holds a particular relevance.
Since I have traveled the world in the Navy, I often can see places and people that I haven't thought of in years as well. I travel without leaving the apartment, and it feels so good.
Music is the greatest creation we have as a species. It is universal and appeals to everyone.
