I am having a problem downloading albums here. More specifically, after I download something, unzip it, send it to a file, and open it, some of the song files on my iTunes cannot be altered while others can. For instance, if I want to change the name of the song, or change the genre or even add artwork it will not let me do it, but on other songs from the same album it will. I am a huge artwork nut and this is killing me. Is this a corrupted file? If so, what can I do to fix this? I have run scans on my computer and my computer is clean....or so I think??? I hope this makes sense. I am a computer moron and have to explain things simply here.
