Radio mix for every and any album, playlist or song

That would be another option called automatic recommendations. You should be able to enable it in the play queue view at the bottom of any played album or playlist, so scroll down to the very bottom of the queue where you can find a switch for that.

Just like in GPM as well.  I use this constantly.  If this feature were added it would also need to be downloadable so that I could listen to the mix on my commute where I have spotty coverage.  I’m currently trialing Deezer, but if they add this in short order, I’ll stick around.

Besides the automated recommendations switch for playlists and albums which I described above Deezer also offers a track mix radio in the dropdown menu of each track which creates a radio of similar tracks.

The Flow is also an endless mix of your favorite songs and artists plus new recommendations.

I’m looking for a mix based on a playlist, not specific recommendations, but based on specific artists in a playlist.  I don’t want an endless flow of all sorts of genres and styles, I prefer, as I’m able to do in Google Play Music, to have a playlist define the scope of the style of music I’m looking for and let the service suggest additional artists to the mix. 

I just tried a track mix on mobile for a track that on the web player track mix is greyed out and the first track it suggested was some rap song. The track I was setting the mix from was an instrumental metal song.  So, that’s not exactly a useful feature.  

Assuming it does work, can I later download the mix so I can play it offline and grow the mix with time?

Also, I have checked the play queue while playing an album and I do not have a switch for automated recommendations.  I am using the Android app.

As far as I know, that switch only exists in the web player and desktop app. Not sure if it will also behave that way on a mobile device after enabling it on your desktop though.

Which is interesting because my target track for the mix didn’t even let me play Track Mix on the web or desktop player but allows me to on mobile then plays a completely different genre.

I noticed a song mix feature has been included, I’m really longing for a playlist mix feature, been a deezer user for 4 years now.

Same here, and it would be great to have access to it from the SONOS app

I was badly messing this Feature recently. Flow used to suggest me some Songs furing Fitness which were quite cool. However I obviously did not remember each and evryone. But from the one or two I remembered I would habe loved to say: Play playlist Based on this Song - just like on the Start Page, just with a Song I choose :)
