Music is written and produced by artists for people to listen to and enjoy. Music is made to be relatable, comforting, exciting, sad, happy, and many other things. The concept of relating music to listeners' emotions helps promote songs and help listeners use music as a form of comfort. Music is most commonly used as background noise when someone doesn't want to be in silence so having a variety of genres help them pick what type of mood they want to be in. The creation process is different for each artist and some write their songs all by themselves while others have co writers. Songs are made to be different from what's already been created, but each artist will generally stick to a specific sound or style. Although even artist's also like to explore outside of their specific style it's usually only until they settle back with their original sound or they stay with the new style if it's working for them.
