Some of my play lists have the generic album art and not the artist album art. These are either disk's i imported into itunes or mp3's I already had. I found a couple of tutorials on adding the art manually, that worked for some of the albums, but I get this error for some " the song "blahblah" could not be used because the original file could not be found. Would you like to locate?". I think the problem is I had some files on my laptop and not on my pc. I was able to mass add album art for play lists, but not for others. I had to do it song by song. Is there a better way to do this?
