I've not had to do this for a while and noticed mp3tag now operates differently than it used to.
I use Cover Art > Discogs Artist + Album option to choose a new cover but now instead of overwriting the cover like it used to, I get options: 'Rename', 'Overwrite' and 'Cancel'.
'Overwrite' does not overwrite the embedded cover but I do get the new cover (folder.jpg) in the folder of the album.
Can someone explain what I'm doing wrong.
