Is there a query field to proof if cover art is embedded?
%coverart% PRESENT
or something like this.
thanks!
Nope.
The foo_covers (http://www.hydrogenaudio.org/forums/index.php?showtopic=71446) plugin adds some titleformating fields which make this possible, eg) %albumart_front% PRESENT. Unfortunately it seems to freeze when searching my full library, but it does work on smaller playlists.
Mp3tag has %_covers% that I use for this purpose. Album Art Downloader, via its File Browser or Foobar Browser, can also find albums that have no embedded art.
