Back in the day your choice of music told the world who you were: mods v rockers, etc. I'm too young to remember but as I understand it Beatles fans despised The Stones and vice versa. I thought both were ancient has - beens, but what did I know in 1972? Pop was always unrelenting awful, no matter what era you choose. Anyone remember the Bay City Rollers? Neither do I, but they were huge for about 3 weeks apparently.
So - modern pop is no more horrific than, say, "The Birdie Song", or anything from Jive Bunny. You shouldn't expect great things from the 2022 version of Bananarama.
The real problem is that marketing is all about £€¥$ and never about talent or creativity. All this means is that you have to go rummaging for the good stuff. It is out there if you can find it - I am currently enjoying this:
However, I'm still listening to all the good old stuff: having an AC/DC revival at the moment, along with Camel and some of the heavierThin Lizzie offerings (Thunder and Lightening for eg) . The real problem is that with 60 years of cracking good music to choose from, new acts have to shout very loudly to get heard.
Personally I was always of the opinion that Lennon & McCartney as a team beat their solo work hands down; neither could capture their unique accomplishments on their own. But the real importance of The Beatles is that without them, we wouldn't have had the music revolution that gave us Jimmi Hendrix, Led Zeppelin, etc., and the world would be a much poorer place.
Just for fun, I shall offer up this which is also on my current play list. "An oldie but goodie".
