Plexamp is really good for this.

The styles information that Plexamp has works really well and in my experience, as long as your library is large enough, works better than modern Spotify.

It was Spotify's degradation of their radio service and terrible "AI DJ" that finally got me off Spotify. Punishing them for platforming Joe Rogan was just icing.

I find Plexamps Radio features, and DJ's to work great against my library. It also helps if you, as an individual, have a diverse and large music library to supply for the sonic analysis.
