A method of browsing a plurality of media items is disclosed. At least one of the media items being associated with a plurality of tag values, each tag value having a level. The method constructs a hierarchical tree structure of tag values according to the levels of the tag values, such that any tag value on any branch of the tree structure from a first tag value is associated with a media item with which said first tag value is associated. At least a first portion of the constructed tree structure is displayed in a graphical user interface. User input is detected to change the level of a second tag value in the displayed portion. The tree structure is reconstructed according to the changed levels of the tag values, such that any tag value on any branch from a third tag value remains associated with a media item with which said third tag value is associated. At least a second portion of the reconstructed tree structure is then displayed in the graphical user interface.
