Is there a way to select multiple tracks and batch update the album art?
I've had several instances where MusicBrainz applied the wrong album art so I found the image on my own. However if I select all the tracks in the list and change the art manually it only applies to a single entry. This forces me to manually go through each track one at a time and Add or Delete each entry.
Sure, the detail panel only ever shows the last selected song. But in the main spreadsheet view itself just copy the coverart from one field to the others and select Paste, alternatively you could use the Set Value option
