In my experience Spotify rules the roost on suggestion and radio algorithms. Rarely do their on the fly or calculated playlists get repetitive or too familiar for me. Other services lag well behind in this regard. Maybe sometime soon they will offer lossless for the audiophiles
I found basically the same with Spotify when I was paying for it. It may have been a little better at it than Tidal but not much IMO. The boost SQ with Tidal More than made up for it.
