The reason there are no radios available in the mass marketplace is indeed due to phones, which are in fact not phones, but pocket computers that are connected to the internet.
The reason there is precious little good pop music past the late 1980's is again, because of computers. I would assume the same technology caused the complete lack of good Television as well. No one can write good wholesome comedy or drama anymore, no one can write or sing good music anymore, so this wonderful beast we've created called the transistor has made people lazy and ignorant.
When the power goes out and the ignorant are separated from the old-school, the first thing they will do is want to Google "how to start a fire", followed by what plants can I eat, and sadly when they remember there is no Google the question goes around the entire group to see if anyone has ever Googled that, and if so do they remember what it said? Of course several actually did Google it at some point in the past, but no-one remembers it because why do you need to remember stuff, you have your phone... you have the internet, you have the almighty Google for that.
All phrased to make a point of course. Yes, it is not our youth that are to blame, they are the victims. Invite them into your home to listen to your stereo. If they have any functioning brain cells left that haven't been microwaved by the phones and cell towers, they will be tickled to see there is something more, something called.... quality.
You should see their faces light up when I pull up to McDonalds in my 70's muscle car. They intuitively know there is something special about it... and become completely distracted with smiles.
My cry in the wilderness is simply the result of watching quality and craftsmanship be replaced by instant disposable crap-for-profit and creating a generation of spoiled idiots who can't write music or television and an ocean full of plastic.

The real cry is for our youth, who have been cheated out of all the good stuff, and it makes me sad when something as simple as a good sounding radio is an alien concept.
