Reviving a somewhat dated thread to expand on the initial question - I noticed that some albums (e.g.
here or
here) have album art that's named 'Front (small)'.
Are these entries separate from the regular ones? In other words, if I notice an album with
xx (small) covers and I have higher quality files available, should I replace the small art with the higher quality one or should both entries be kept because they are separate categories?
