I figure in the OP via a link to my Youtube Channel. Apparently this is supposed to make some sort of point relating to the topic of this thread ~~

Not quite the OP anyway, Michael - and as CJB said above I find a parallel here with Western [...] folk music [...] that raises the emotions, and lifts the 'feel good' factor. So there you have it! My point was that I reckon it's easier for Western Ears to get this from a YouTue vid of MtheGM inbibing his magic-potion and singing Butter & Cheese & All than that of an Amazonian Shaman puffing on his magic jungle-weed singing something similar. Otherwise - yes, indeed, I'd all music operates on this level; and Shamans are the players who make it so especially potent...

I would also point out that in my other life as a Storyteller I'm acutely aware of the Shamanic value, origin and potency of the Indo-European Folk Tale, and of Traditional Balladry too, all of which act as essential distillations of healing ritual to work on an individual, familial or societal level. I knew a young Shaman once who, after many miscarriages, sang Child #6 every day throughout her pregnancy and was delivered of a healthy bouncing baby boy.
