How can I determine what stations I want to associate with on my account? I upload my tracks and once they have played, other people's tracks start playing that I have never heard, never chose their stations; some are tracks I would never want to be associated with in anyway. How can I delete them. If the answer involves having something other than a free account, I will have to consider deleting my Soundcloud account so that I am not introducing crap to others who wish to access my music. Thanks.
