When I indicate I do not like a certain song within my radio station that you have selected, why do you play that same song later, usually on the same day? I want that song or artist deleted permanently from my playlist when I indicate i do not like (thumbs down). Is this something you can do? I tried the pay service and it was the same so I cancelled my subscription.
Radio is not spotify's best feature I'm afraid. Everything else about the music service including delivery speed and quality is awesome but, if radio is your main interest, there are maybe more appropriate services out there at the moment.
