soul, what the hell is it anyway?

Tom's taxonomy is as super-useful as ever. I think that "pop" and "rock" are in fact more specific than the fourth definition of "soul". But, more importantly, perhaps we can view all three words as in fact invoking a different 'aspect' of the same musical act. Seen from the pov of the listener (i.e. awed by the mysterious "soul") the pov of the musician (gap between audience and artist is narrowed by the act of "rocking out" -- c.f. Lester Bangs on The Stooges) and the 'impartial' pov of the media (If something is 'pop' then that's just another way for saying it is a pure commodity, and thus it is judged on the terms in which society judges commodities -- it is not an act but a recognition of social "popularity").

Yes: woolly hats off to Ewing. He should be in Forensics.
