So I have searched this question may times and I still cannot find an answer. What I have seen tells me to go to station details and then swipe from right to left across any band I do not want feeding. This motion is supposed to unveil a button that says remove but so far the screen has not changed. Is there something else I need to do? I'm really quite tired of hearing "Soul Sisters" on my Disturbed radio station.
I had this same problem and wrote to Pandora. Their response was: "It sounds like you need to check the bookmark that you use to access Pandora.
It should ONLY be: http://pandora.com
If there is anything added onto it (ie: http://pandora.com#//genres/top) then erase that. That is most likely the problem.
Hope this helps!!
