Shula, I will be happy to have us go on adding examples. I 'm not sure why that precludes discussing the context of the examples.
This inclusion/exclusion issue is a subtext of quite a few of the discussion-oriented threads. Personally, I'm in favour of as broad an inclusion as people want to make, whether in the context of what is "folk", what is "blues", or what is "arts and crafts". I suspect that most of us are. But the inclusion/exclusion issue also arises implicitly when we get into the "humourous" discussions of tasteless music and schmaltz. Essentially, those discussions make something akin to a distinction between "art" music (what we like) and "craft" music (what a bunch of other people like so much that it gets played a lot and we don't like it). That's one of the reasons that I am less comfortable with those "humourous" discussions.
