Radio/Stream conposed of selected Artists

Coming from Youtube Music. What I really miss is the feature to creat a Radio/Endless Stream of music with a Selection of Artists of my choice. Also you could set up how much variety you'd like to have (how much other artists, or new music you want to have mixed in)

It’s a neat feature and I think if fits well into Flow. Similar to how you can now select genres for flow. Instead it’d be amazing if we could select artists as well 

With the options for little/muchvariety - sometimes you just want to hear your favourite artists, sometimes you're ready to explore
