System and method for playlist generation based on similarity data

摘要

System, method and computer program that encompasses one or more client devices cooperating with a program host's on-line data processing center for making purchase recommendations of media items to a program participant. Accordingly, there is a transmission from a program host to a program participant of identification of at least one recommended-for-purchase media item selected based on the recommended-for-purchase media item being rated as similar to a designated media item presently contained in an inventory of a media library of the program participant. The rating of the recommended-for-purchase media item as being similar to the designated media item presently contained in the inventory of the media library of the program participant is representative of a frequency at which the recommended-for-purchase media item co-occurs with the designated media item in media libraries of others.
