Comment 1 for bug 514664

The order is:
 - from cover cache (ie: ~/.cache/listen/cover/)
 - from some filename pattern in the music directory (ie: cover.jpg,folder.jpg, and many other)
 - from id3tag
 - from audioscrobbler webservice
 - from amazon webservice

I think a good way is to check id3tag before pattern in the music directory

You can disable "filename pattern" by edit "/usr/lib/listen/cover_manager.py" and replace:

COVER_PATTERNS = [
    "cover.jpg", "cover.png",
    "*front*.jpg", "*front*.png",
    "*cover*.jpg", "*cover*.png",
    "*album*.jpg", "*album*.png",
    "folder.jpg", "folder.png",
    ".folder.jpg", ".folder.png",
    "*artist*.jpg", "*artist*.png"
    ]
