This is what I would like to see in the playlist radio station:
Option for "Don't play songs already in my playlist".
Option to "Add liked songs to the playlist".
Option that lets you say "I'm tired of this song" (this should be for all songs in spotify).
Liking and disliking songs should be reversible.
I know the spotify radio algorithm has improved a lot. But when I'm listening to a radio station started from a playlist, the majority of the songs are what's already in my playlist. I don't "dislike" these songs, it's just I'm tired of listening to them or want to discover new music. This would really allow a personalized “discover new music” that’s doesn’t require any effort. Maybe adding this feature to spotify premium would be another incentive for people to become join spotify premium.
Recommended Songs are great except I can't "dislike" songs and refresh keeps bringing back those songs.
