One thing about the expression "people of colo(u)r" is that it does serve to indicate whether the person posting is North American or not.

While the emphasis of musical discussion here tends to be North American music and music from the British Isles (not at all the same as "British Music"), together with other Anglophone communities round the world, its by no means restricted to that.

There are a myriad varieties of other great folk music traditions around the world, and they all have a place here. (And most of them have been produced by "people of colour", a category which includes by far the bulk of the human race.)
