I always find these takes curious because they could not be further from my experience. I'm still discovering tons of good music. Perhaps it's specific to genres, but I haven't encountered any generated junk tracks.
It depends on the algorithm which often preferences "similarity" (for whatever definition of similarity is).
This year I got into some pretty generic blues/rock when driving and really liked one of the songs in some playlist/radio [1]. Little did I know that the song was AI. So when I started a radio based on that song, the resulting radio was 99% AI though I didn't even realise that until after a second/third listen through.
There's also obvious care and human creation there as well.
They have several "artists". Bertha Mae Lightning gets the better lyrics and artangements. Virgil Dillard gets simpler tunes and the occasional weird grammar/lyrics. And so on.
Really? How about asking google to "play bloomberg news on spotify" next time. Then see if you can remove the resulting chaos from your history so it won't start feeding you slop.
