A processor retrieves, from a database, an identifier of a first media item rated by a target user, user identifiers of users having provided media item ratings for the first media item, and the media item ratings provided by the users, correspondingly. Each of the media item ratings is randomized, resulting in randomized media item ratings. A user identifier corresponding to a maximum of the randomized media item ratings is selected from the user identifiers. Additional media item ratings associated with the selected user identifier are retrieved from the database. Each of the additional media item ratings are randomized, resulting in additional randomized media item ratings. An identifier of a recommended media item corresponding to a maximum of the randomized media item ratings and the additional randomized media item ratings is selected. Metadata associated with the recommended media item is transmitted to a user device over a network.
