Whatever criticism we may have for Jonah, at least it can be said that Jonah was consistent. This legalistic, over-judgmental, young prophet will consistently proscribe the most severe form of punishment for the guilty--even when the guilty party is himself. The young Jonah hijacks written Torah to condemn everyone--even himself.
People listening to songs are like people reading novels: for a few minutes, for a few hours, someone else gets to come in and hijack that part of your brain that's always thinking. A good book or song kidnaps your interior voice and does all the driving. With the artist in charge you're free for a little while to leave your body and be someone else.
