Artist Radio Playlists vs Normal Artist Radio Stations - difference?

[ACDC-Fan]

On the Home tab now I have a section called "Recommended Radios" which has a choice of "Non-stop music based on your favourite songs and artists".

However these seem to be completely different to to ordinary Spotify radio stations in that they appear to be publicly followable and furthermore they don't appear in the Stations section when I follow them - they seem to be Playlists.

I'm fine with this but are we supposed to be using these playlist Radio stations now instead of the other Radio stations that you can listen to?

If I search for an artist the "Artist Name Radio" playlist appears in the search results so does this supersede the other on-demand radio?
