Instead of having (or in addition to having) discover weekly playlists, there should be 3 or so playlists of recommended artists. Each playlist would be dedicated to one recommended artist and consist of songs that the user may enjoy by them. This is because discover weekly helps in finding new single songs but isn't as helpful in finding brand new artists, especially smaller artists.
We set this to IMPLEMENTED since such playlists (based on artists you might like in connection with other artists you listen to) are already featured in Home. These playlists' name always starts with "This is..." and has the name of the main suggested artist.
