I'd suggest that this isn't a recent phenomenon. I've got plenty of
pop
vinyl from the 1970s and 1980s that has roughly no dynamics.




Yep, you bought it so *they* kept on supplying it - same thing's
happening today, apparently. Where's the problem?


Making crap
sound louder on the radio at the complete expense of quality is
decades old.



Compressed audio like 'Classic FM' on a car radio works very well,
actually....



Not so well when they play MP3 versus CD cuts. Locally, the oldies station
WZBA has enough crunch on their MP3s that I can't really crank a CCR tune as
loud as I want in the car because the distortion stops me. That's just a buzz
kill. (could be another problem in their audio chain, but I don't think so.)


The problem with radio processing is that MP3's and other data reduced
sources do not process very well. Its akin to taking a 2 M photo and
expanding it up and then comparing it to a 10 M

Least radio 3 use linear PCM for their source audio, some other
broadcasters don't see it that way!.

And Klassick 'eff em is too far processed anyway!..
