Years ago, I posted this problem:
http://yabb.jriver.com/interact/index.php?topic=66932.msg448893#msg448893, where several of my albums incorrectly use the cover art of another album.
This has continued to happens with every version of MC since, including 19. Every time I upgrade, it arbitrarily finds a new album to use for the bad placeholder image. I always thought this was a problem with MC because Windows Media Player does not have this problem.
Well, it turns out it's not exclusive to MC. This summer I loaded up MediaPortal and observed the exact same problem. So, I thought maybe my files were corrupt (they play fine). But, some of the files with this problem are WMVs and some are MP3s, so I don't even know how different formats could have the same weird problem (if it were a file problem) and I don't know how two totally different applications could have the same weird problem (if it's not a file problem).
Any ideas as to what might cause this? Thanks.
