Text: Music is always telling stories (more or less), and I think that charismatic power is an element in one of those stories--the force we feel when a strong personality comes up against a demonic power and refuses to be cowed, and takes hair-raising risks, and succeeds in being, if only for a moment, the demon's equal.
Entailment: Charismatic power is an element of music, I think.
Contradiction: Music seldom tells stories, and I think it lacks taste in general.
