Although, I’m pretty sure there’s a ton of really complex and difficult jazz out there (IIRC it is one of the most advanced genres, whatever they means; I don’t do music). But that isn’t what we’re looking for on the chill whatever ambient music channels.
My Discover Weekly from Spotify used to be awesome. I found a bunch of new artists that I really liked and tons of great new songs. Recently it's been a bunch of old stuff that I've definitely heard of before. So I've mostly stopped listening to it.
Discover Weekly went from something I was excited about every Monday morning on the train, to something I forget to check most weeks.
There's a handful of songs it puts on every few weeks, for literally years now, despite me skipping them every time and never once listening to the band or song by choice.
And in the end, the real money for musicians is syncs, shows and merch anyway. Spotify streaming revenue is tiny in comparison.
A wether is a castrated ram.
"jazz improv" is probably just that, start with a generic beat / atmosphere and improvise and noodle on top of that. Sounds great to me, I wish there was more low barrier to entry live music like that. But I suppose there's no market for e.g. an in-house band working shifts for background entertainment, and they can't compete with jukebox software.
