Music has helped me and many other people through depression. It helped me get over my first broken heart. It helped many others get their feelings out. It helped my brother destroy my own soul. It is truly a beautiful thing.
I play guitar and bass for myself. When I'm kicked out of my house to live a stupid life on my own, I will have a certain advantage over several other people. The ability to enjoy and play music is something that many people can't enjoy because they decided to not follow through. Without music, the music industry and the general love of music, society is incredibly boring. Many would be driven to other ways out if there was no beat to go by.
TL;DR, Music is a truly beautiful thing: It can both help and hinder, make love and hate, but most of all, it is one of the purest forms of art. From tribal beats to classical to Rock n Roll to electronic to heavy metal, let us keep the beat going.
