Music is more than just something we listen to. It plays a special and essential role in many of our lives. Think of a film or show running without music. Think of an advertisement or a sports event or a concert (of any discipline) or a meet-and-greet or a restaurant or so many contexts where without the soundtrack there to support and enhance the mood we would feel almost uncomfortable in the quiet.

Music moves us, builds our confidence, heightens our emotional sensitivity but mostly music provides meaning where the point might not otherwise have been made. A perfect song, a well timed chorus, an album that succinctly captures a moment (that can be revisited with nostalgia whenever that album is heard again). 

I would say for this reason and so many others, music is essential to us.
