Who is the authority in the field of art? Is there an authority? Should there be an authority? I guess there is no authority in art and there should not be. The problem behind the beef between Nicki Minaj and Peter Rosenberg is that when celebrities have influences, they want to become the authority and the representative of their specialized field of art. Although they are not being real authority, being authority at least in some ways might give people a false feeling of having power. People feel good about having power. In the case of Peter Rosenberg, he believes he has the power to decide what is true Hip Pop and what is not, because of his "legitimate" background. However, how can you tell why Nicki Minaj's songs are not Hip Pop?
Art is changing and its genre is changing too. Unlike engineers, doctors, archaeologists who work within stipulated traditions and science, artists don't have any boundary. We create according to our visions and what makes artists most proud of is there are people believing in their visions. That is what matters. However, a tendency of complaining still persists.
Art is self-defined though, old influential artists do feel shamed that recently the self-defined art becomes more and more shallow and uninspiring. Influential director Martin Scorsese wrote an article on the New York Times, expressing his concerns because of Netflix and Marvel superhero movies, filmmakers and audience start to treat films as good to cater people's demands. The true soul of films is lost. When everything is so accessible on the internet, the amount of time people would devote to appreciate a piece of art shrinks severely. Artists have to make high-stimulating contents (sex, violence, gun) to attract people's attention. Then people tend to only appreciate art that is high-stimulating. An endless loop it is. Art is not just entertainment. It is also an appreciation and appreciation takes time. Art can only be deep and inspiring, when people spend time on it but most people right now have "no time."
