Embodiments of a media user interface are presented herein. In one embodiment, a plurality of representations of media items is arranged into a plurality of groups such that the plurality of groups of representations are horizontally navigated like a carousel. In another embodiment, the plurality of representations of media items is presented based on user selection of data associated with features of the media items. Yet in another embodiment where a plurality of representations is vertically aligned, navigating a representation causes vertical space between the representation and another representation next to it to be increased and causes representations of a sub-category of the representation to be displayed within the increased space.
