Abstract: Media players and associated methods are described that may allow a user to navigate content or other media assets. A media player or portable media device, can include features for generating and utilizing navigation information for navigating content, such as audio books. An audio book may be analyzed to determine one or more locations within the audio book that represent chapters, paragraphs, sentences, or the like. Navigation information may be generated indicative of the one or more locations that may be used by a media player or portable media device to play content in the audio book. The navigation information may include audio clips extracted from the audio book to represent the chapters and the like. In addition, a user may navigate content in response to predetermined user motions. A media player may scroll through content based on the predetermined user motions.

Abstract: Media players and associated methods are described that may allow a user to initiate playback of content or other media assets based on information associated with content. A media player may receive information associated with content from a user selection of a song, movie, photo, or the like. Based on the information, the media player may procure other additional content to be added to a playlist. The media player may automatically add to a playlist or modify a playlist with content that matches a user's preferences for artists, albums, genres, or the like. The user may interact with the media player to determine what content is added and how a playlist should be mixed. The user may specify how much of any content procured by the media player should be present in the playlist without the need to specify each individual item that constitutes a playlist.

Abstract: Media players and associated methods are described that may allow a user to organize content or other media assets based on information associated with content. A media player or portable media device, can include features for automatically tagging content or other media assets with aliases. A media player may receive content that has already been tagged with a given alias. The media player may determine a macro genre for the content in response to a set of rules. The rules may include criteria for classifying content into one or more macro genres. The media player may generate information associating the macro genre with the content.
