I have mutliple drives. My preference because of backups etc is to keep the artwork within the file tags!! I have 2 issues:
1) When I copy these MP3s to another drive (and delete the originals), then import the new files in to MC, the artwork is not present within MC. However, when I go to windows explorer, the album art (ICON) is right there with the MC trademark in the bottom right corner. It appears that having the artwork in the directory is still a requirement even though it is within the file itself. Now in anycase, why doesn't this album art show up within MC after a new import?
2) Since I do still have a legacy file art directory. When I take an album and update any tags I would think that that existing correct artwork, from the directory, would then be updated to the tag in the file. That is not the case. It looks like have to have the artwork stored in the file I must explictly explicitly right click >cover art> etc.... as opposed to other tags artist, album.
FYI I do not have the portable version of MC as I have not really seen a detailed description of the differences between the standard and portable.
