Artwork from tags should always be shown, are you saying it's not? Ie. Properties > Artwork doesn't show it all?

If so, which build (Help > About) of MediaMonkey and what file type(s)?

How can I tell MediaMonkey Desktop and Android to retrieve the artwork from the tags—that is, from the file itself? Currently, it always retrieves it from the directory, which means I often see the back of a CD cover.
