Sometimes the spinner icon is not automatically cleared, usually because the update happens very quickly. It can be manually cleared by clicking on any of the toggle buttons below the volume knob. You can always verify that the update has completed by examining MPD log. cat /var/log/mpd/log.

Since the Library and Album panels are based on Genre/Artist/Album tags, any missing tags will cause problems. Missing tags are assigned the string "Unknown".
moOde uses the Zend Media class framework to extract cover art from mp3, flac and m4a formats. I'm not able to debug that framework to determine why its not able to extract a particular cover. IME though its rare for it to fail and if it does its typically due to some sort of corruption in the song file or tag structure.
The Library List and Album Cover panels and the Thumbnail generator assume a standard Artist/Album directory structure. When an Album is clicked in the Library List panel the first song in the Album directory is used for extracted cover art. The Thumbnail generator uses the last song in the Album directory for embedded cover art.
A directory containing songs from different Albums, often used to manually form compilations, is not compatible with the Thumbnail generator and Album Cover panel.
