A user interface allows a user to access media items by selecting from a list of thumbnail items associated with the media items. Various techniques are used to reduce the latency times when displaying the list of thumbnail items in the user interface. When the list is initially displayed, for example, the thumbnail items may be loaded into memory according to how far they are from a currently displayed portion of the list, rather than always starting from the top of the list. In addition, if not all of the thumbnail items can be loaded at one time, when the list window is scrolled, the thumbnail items relatively far from a current scroll position of the list are purged so that the items closer to the current scroll position may be loaded.
