Yes, I feel like Spotify's algorithms have become good at giving more of the same but worse for discovery. I don't find as many new artists as I used to. And some songs just come up again and again, which I guess are paid promotions.

I've mostly switched to Qobuz, which doesn't have as many auto-generated playlists as Spotify, but can auto-play similar music once your selection has played. Qobuz's emphasis is more on listing albums you might be interested in and having you choose which ones to listen to. I'm discovering more new music this way than through Spotify.
