Automatic generation of online media stations customized to individual users

An online media station can be automatically generated based on a user's media preference data. Media preference data can include a user's media item purchase history. The media preference data is analyzed and media preference clusters are generated from the analyzed media preference data. Generated media preference clusters are ranked based on a predetermined set of ranking rules. The top ranked media preference clusters are selected dependent upon the user's number of slots available for customized media stations. One or more media station seeds are selected from each media preference cluster selected based on a set of predetermined selection rules. An algorithmic media station is automatically generated from the one or more media station seeds and provided to an electronic device of the user.
