I think one of the differences between good art and great art is that good art is enjoyable once you’re already in the mood that it was created for—like club music when you’re drunk or academic writing when you’re up early drinking coffee.
Great art gets you into the mood whether you’re already there or not. You could be sitting at your desk at work in the afternoon and read a great poem and all of a sudden you’re transported to an emotional state where you’re almost crying.
For good art, you have to be there already. Great art takes you there.
