Flexible methods for cataloguing metadata and for specifying a play queue for media systems

Abstract

A flexible method for cataloguing metadata makes it possible for users of digital media systems to define the set of metadata tags that best describe recordings within each genre. Tagging recordings with appropriate metadata facilitates selection of a desired recording. In addition, flexible metadata tags minimize the display area required to present information essential to selecting the desired recording. A flexible method for specifying a Play Queue makes it possible to queue items comprising Collections of Tracks. Tracks can be collected according to various criteria. One type of Collection simply lists the desired Tracks from a single album. Other Collections specify Tracks based on a search of the catalog, a random selection from the catalog, or a previously saved list. Collections maintain their identity in the Play Queue, so users can easily modify or remove a Collection or change the sequence of Collections.
