Lots of good new music around for most / all tastes imo.
You've just got to find it.
90% of everything is crap. Always has been.
This seems correct to me. I don't know if it's 90% or what, but all the good stuff (and some not so good stuff) is curated for posterity and presented as the sum total of music from an era. Sometimes, most times, the curators even miss out good, less well-known stuff when recycling opinions over and over. When I was young I'd never heard of John Martyn, it was the internet that brought his music to me and I was pointed to it by someone younger than me!
I find there are young people listening to both new and old music since the access to music exploded. And it's not easy to produce new and exciting popular music decades after it got going and where a lot has already been done. I'm also willing to entertain the idea that music is at least 50%, if not more, about experiences. So you always associate music from when you felt young and hopeful and possibly in love etc. So it means more. My grandad told my father the Beatles were rubbish, Then 25 years later said
Yesterday and
The Long And Winding Road were ' good songs'...even though he was listening to the James Last interpretations...
One of the reasons I watched Later with Jools Holland was to see new/less well-known artists. Back in Blighty I used to sit in my old piano tutor's parlour and his dad (gypsy violinist and ex-gas meter reader for the gas board) had the telly on and his feet on the fireplace and at 88 years-old he would sit there and say things like: 'she has a good voice' and 'there are lot of young-uns who know what they're doing'. There's no excuse for not having an open mind to it.
