Back in the late 60s my family (I was a teen) was contacted to be a "Nielsen family". After the month long trial was over they they told us "Thanks, but no thanks. Your viewing habits are too different from the norm."
You know if they get too many people that aren't just "cardboard cutouts" of the ideal consumer,
they might have to admit the world is not just two dimensional.
I can't stand listening to music on little private thingies.
That's why my private music runs on automation, extreeeem processing, gentle but huge reverb, tight cuts and commercials I want to hear,
then runs on pt 15 AM so I can listen to them on the many radios, table, bedside, backyard around the place.
Nothing sounds better than music on a great AM radio.
I've tried to make other sources sound as good, but there is no substitute for a perfect 150% positive modulated AM signal.
Unless it's a great recording of a perfect 150% AM signal.
I wonder if it's less about radio vs other modes as it is about "the masses" becoming accepting of whatever is sold
without regard or consideration that there ought to be standards of some sort.
I'm dancing around but avoiding the "q" word.
I can't accept any headphones for listening. I love them for TASK work, if they're my expensive old Sonys.
When I am listening I MUST have a loudspeaker/cabinet of some minimum size before it is a "radio" and out of the "portable radio"
category. This happens at about the size of an average box of tissues.
The younger set seems to be able to tolerate the boom and rumble of single wire headphones from physical movement and friction.
I find the music completely overpowered by such noises unless I sit perfectly still to listen.
This is why I prefer my music to follow ME around the room, as happens when the radio is on.
When you turn on a really physically LARGE radio like some of the top-end mid-1930s consoles, a very modest volume
fills the entire house in a way that is very very different from the headphone or tiny clock radio perception of radio.
A friend just brought over a very early General Electric transistor portable a "potential girlfriend" of his just bought and would like aligned and
put into shape. I'm guessing its about 1959 or 1960, and it has a balanced armature speaker instead of a moving solenoid "voice coil" type!
Anyway, this lady is in her late 30's, and is engaged enough in radio to seek out a 50 year old AM radio and find
someone to repair and align it.
I won't use an anecdote to extrapolate what others do, but returning to Pirate Johnny's comments, there is a lot more
variation than metrics methodolgy wishes to admit. It would just be too hard a job unless "preconditions" are gently maintained
to ensure the measurement serves certain perspectives.
