LOL... we are talking about people here... both those making music and those listening.

People are multi-faceted not little cardboard cutouts. Each brings their interest, background and experience with them. We can't help it- it's who and what we are.

What may entertain one person, bores another to death. So it you try to come up with definitions, you need to find ones that work across the board, and there needs to be agreement about the meaning of the definitions... otherwise it's an exercise in futility.

Add to that the lumpers and splitters... LOL.. I grew up listening to "classical music"... in reality, I was listening to music from the baroque, classical, romantic and modern periods. But the convention is to lump them all together into the generic term "classical music". As long as you know the "rule" of the definition.. no problem.
