I'm trying to add an album to my itunes library (running 7.3 on Windows XP). I've tried: File > add file to library; File > add folder to library; drag and drop ... nothing works. All of the files are .mp3. I've even tried renaming and retagging the files. All of the songs play fine in Winamp, and I've successfully added full albums before and after this attempt. This is the first time this has happened to me and I can't figure out why. I've seen similar threads, but I haven't seen an answer, sorry if I missed it.
