Don't understand what RB thinks I'm wrong about. That I prefer to describe music with a few explanatory words rather than with one almost universally misunderstood, misinterpreted and terminally bankrupt one?

Apart from which, of course I am wholly with Jim Carroll. Including the bit about "passing a test", which I think should be a self-imposed standard as far as public performance is concerned. Don't play or sing out till you can, because the shambling, half-forgotten words, key wandering and duff notes are yet another reason why Joe Public gets the impression that the music is some kind of joke. No-one should do it such a disservice.
