It would be great that MusicBee will search for the album art (especially from sources like Google) not just by the default 'album' pref. but based on the users' choice also for the artist, genre, etc.
This is useful where the album has names like 'Now that's what I call music' or 'Rock Christmas' when you could want a more personal look to the tracks.
Thanks for the continuous good work.
edit: Though I don't like 'Last.fm' for artwork based on 'albums' I am sure it would be a great source for 'artist' based art.
