Abstract: A system and a method enable browsing, selecting and/or controlling rendering of media with a mobile device. Content from multiple content sources is aggregated, and a default content source and/or a default rendering device used for subsequent media selection are established. Individual media playback shortcuts are associated with specific default rendering devices. A user may navigate within a collection of content without a need to repeat full content browsing and selection. A user interface of a multimedia player and/or playback controller on the mobile device displays active metadata tags. By selecting an active metadata tag, the user may access a list of associated metadata tag values. By selecting a tag value, the user may select a set of content associated with the tag value for rendering.
