Discovering content on a device. Content stored on a device can be examined or searched based on the programming of channels that are available to the device. The content can be searched using other rules related to user preferences. Based on the results of the examination of the content, playlists are generated. Each playlist includes content from the device that matches or partially matches the content associated with one of the channels. Using the playlists, a user can load content from their device that has a theme consistent with a particular channel. The playlists can also be used to tune to the channels associated with the playlists and thereby discover the content on those channels.
