So should we give up just like that? Can't we analyze the music? Can't we interpret it? Can't we read what the artist has written and listen to what he has said? Cage may have been just trying to be different, but what about his Buddhism, nichi nichi kore kōnichi and all that? There are plenty of things he was trying to express through his music. And minimalism did catch on. Again, art vs. entertainment. The bearing on the music in your scenario is that you, the artist, failed to achieve your goal. Unsurprisingly, the music was poor as a result.
