I’ve already tagged my albums via Picard, but now I’ve changed some settings, so running albums through again. For some albums, Picard was unable to provide cover art, and so I add manually via Picard (drag and drop). The problem I’m having now is Picard keeps deleting, or rather refuses to keep current art work for those albums where I had to add manually. I tried disabling ‘Cover Art’ options one by one, until now nothing is selected, but still art work is removed.
Is there anyway I can re-tag and keep currently art work please?
