I am getting frustrated as songs that I have thumbs downed have continued to play, I even started to keep track of them and one song I have thumbs downed 5 times! Why does it say it is "improving station" and I am encouraged to use the thumbs up/down to help it play music I like better, but yet it insists on playing music I have thumbs downed, not only once but multiple times?

I can understand if it plays other tracks from the same album or from the same artist as music I have thumbs downed, but this is getting quite annoying as it doesn't seem to be learning an iota about my music tastes.

Any suggestions to get this program to stop playing music I clearly dislike?
