I'm going to simply copy and paste some of what I wrote there to start with:
That was two days ago. And then I started reading a horror novel last night, and this is what I came across......What i find more problematic is that, because of the way things are now, people get to hear a much narrower range of music than they used to, and they see a much narrower range of film and TV than they used to. When I grew up, there were four TV channels, and if it was a rainy day in the school holidays you had a choice of an Elvis film on BBC2 or a Judy Garland film on Channel 4! So you watched one or the other. Now, people often find their own niche on a cable channel or Netflix etc, and watch what they already know they like. Therefore they're not exposed to a lot of stuff in the way that people my age and older were.
The same is true with music, I think. People can listen to the Elvis channel - or, indeed, the Sinatra channel - on something like Sirius, and only hear music that they already know they're going to like or be familiar with. Or they can ask Alexa to play nothing but Justin Bieber all day. But ten or twenty years ago, if you had the radio on, then you were likely (in the UK at least) to hear quite a range of songs - even if it was a chart station like Radio 1, you'd hear rap and rock and pop or whatever. Now, you can just tune out all the bits you don't want to hear and go off and hear only what you know you like. And I find that rather sad.
That makes me sound like a "days were better when I was young" old fogey, and I don't believe that for the most part, but I think exposure to something is important - and not just Sinatra, but anything. And I think the trend over the last decade or so for governments to view music lessons etc at school as relatively unimportant means that lots of people never get to hear anything new that might inspire them. I was so lucky when I was eleven to go to high school and have a great teacher of classroom music lessons who I somehow connected with and started my journey into classical music. But without that exposure to those pieces we examined in class (Danse Macabre, Vltava, Till Eulenspiegel etc), that never would have happened - and I wonder how much harder lockdown would have been for me if that wasn't the case.
It's a complete coincidence that I came across that by accident just after writing the other comments.
