Abstract

A portable digital media playback apparatus is disclosed. The device comes preloaded with a large number of digital media files for preview. After preview, the files are tagged with information that indicate that the user wishes to purchase the digital media file or purchase certain digital rights associated with the digital media file, such as for example, rental to play the media three times. When the portable device is synched back up with a library of digital media files available for purchase or rental, the files designated for purchase are downloaded to the portable device and files designated to be deleted are deleted from the portable device. In one embodiment, a user profile is created and includes a record of user events relating to the digital media files previewed or deleted or selected for purchase. The user profile is then provided to the content provider to compare it with the characteristics of additional digital media files available for preview. The content provider adopts a set of criteria for matches and with this policy or business rule creates a list of additional digital media files that are compatible with the user and which will be pushed down to the portable device the next time that the user synchs up. The user profile information from multiple users can be aggregated and stripped of the personal information to deliver valuable market research data to participants in the digital media marketplace.
