My account has been hacked. This problem has been solved in the meanwhile. However, the user which has used my account has a totally different taste of music, and he was listening to a lot of songs. Therefore my mix of the week from Spotify was getting useless to me - unfortunately these other songs are taken into account for the weekly mix. How can I get in contact with Spotify to "clean" or at least "reset" the underlying song list for the algorithm? It would be great if only songs are taken into account, which are currently in one of my play lists.
