Abstract: Systems, methods, and computer readable storage mediums are provided for selecting a media content object for a user using a combination of inputs. A media input seed associated with a user is obtained. A plurality of channels of media content objects is obtained. At least one of the plurality of channels is associated with the media input seed. Also, in some embodiments, each media content object of each of those channels has a score specific to that channel. A combination score for a respective media content object is calculated based at least in part on that respective media content object's channel specific score for each of at least two of the plurality of channels. Then at least some of the media content objects are ranked based at least in part on their respective combination scores. Finally, at least one ranked media content object is then selected for transmission.

Abstract: Systems and methods are provided for personalizing new song suggestions for a user. A plurality of users provides thumbs up and thumbs down ratings for a pair of songs (song A and B). A first aggregate rating for song B is calculated based on ratings given to song A by all of the users that gave a like rating to song A. Similarly, a second aggregate rating is calculated for song B based on ratings given to song B by all users that gave a dislike rating to song A. Then a user that has not previously rated song B, supplies a rating for song A. A prediction is performed of how the user will rate song B based on the user's rating of song A. For example, the first aggregate rating for song B is used if the user rated song A positively.
