15. A computer system for enabling a user to select one or more items from a plurality of items, comprising: a processor; a storage system for storing the plurality of items; and a display having a user interface controlled by the processor for enabling the user to access the plurality of items in the storage system, the user interface presenting the user with one or more selectable mood identifiers for selection by the user, wherein each selectable mood identifier among the one or more selectable mood identifiers includes a first range of intensities of at least one mood and enabling the user to select a first point within the first range, the processor automatically generating a first span around the first point, the first span including a first subrange of additional points within at least the first range on at least one side of the first point, in response to the user selection, the processor searching the plurality of items in the storage system, each item among the plurality of items having been assigned one or more pre-determined mood identifiers by an entity other than the user, wherein each pre-determined mood identifier among the one or more pre-determined mood identifiers includes a second span representing a set of additional points within at least a second range of intensities of at least one mood, as a result of the searching, the processor generating a list of items corresponding to the one or more items where the order of the list of items is based on a level of correspondence between the at least the first span of one or more selectable mood identifiers selected by the user and at least the second span of the pre-determined mood identifiers assigned to the items, and the processor presenting to the user through the user interface the list of items.
