            ``sticker list {TYPE} {URI}``

            Lists the stickers for the specified object.

            Searches the sticker database for stickers with the specified name,
            below the specified directory (``URI``). For each matching song, it
            prints the ``URI`` and that one sticker's value.

            ``sticker get {TYPE} {URI} {NAME}``

            Reads a sticker value for the specified object.

            ``sticker set {TYPE} {URI} {NAME} {VALUE}``

            Adds a sticker value to the specified object. If a sticker item
            with that name already exists, it is replaced.

            ``sticker delete {TYPE} {URI} [NAME]``

            Deletes a sticker value from the specified object. If you do not
            specify a sticker name, all sticker values are deleted.
