Weird, I switched to Spotify once Google Play Music (or whatever silly name it had when Google ate songza) became YouTube Music because I found it such a poor experience.
Perhaps I was missing something but the change def did not improve the recommendations - it made them drastically worse.
In my experience, Spotify's recommendations are good for a few months, and then stick in a rut at some point for reasons I don't understand. So you're probably in that nice honeymoon phase where it's actually allowing you to discover new things instead of surfacing the same 20 artists over and over and over again.
For me Spotify was discovering good new music for years before getting “stuck” recommending the same artists over and over again last year. I do mark them as “I dont like this song” but it still will recommend them later. I think it’s time to reset and start over.
