anchor: 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.
positive: Stories can be told by music.
negative: Music doesn't tell stories, but just makes people happy.
