genre

I think that what makes a class of genre is a common theme in many different artist's work. It could also be that the artist created the genre and many had the same idea at that time just in a pinch of a different way and then made it a genre. Artist for the most part make up the genre, but I don't believe that they planed it that way. It is cause people are obsessed with categorizing things that we made it a genre and took away from some of their art from doing this.  The only purpose that we have genres for is for the sole purpose of writing it down in history, so many can learn off it and put it in a section where people can find things easier, faster, and find others just like a artist.
