For me who do not understand anything about music, it's hard to judge good music based on musical techniques, the combination of the tones contained in it, as well as other things that are technical. Although it may seem to simplify the process of music that occurs in the cultivation of a work, for me a good music is music that can give meaning when listening. This is where art is interesting. Because art is not science, art seems to give the audience a kind of freedom to analyze and interpret the stimulus presented without stuck to the rules and laws that usually become the benchmark of science in trying to explain the world.
