You just beat me to the punch with that elaboration there, Ray

I think this whole thread just underlines a need I've seen in other threads, for an overhaul/update to these definitions. To give the user more varied set of
choices, a bit like they're already offering with the various ways for us to define chords. Perhaps a sort of "Define terminology in Jazz or Pop" kind of settings for the user might be just the thing here.
EDIT: And needless to say, this should be song based, not ruined by a crude Global implementation (which happens too often!)
