When I ask Picard to lookup a mp3 I just recorded from the web, like from Spotify it finds the wrong Artist/Title in some files. When I correct it manuly and recan it it puts back the wrong one again. ANNOYING! Is there a way to tell Picard that what I manuly put in is correct? I went to Amazon to look up the correct Artist/Title and Picard switchs it back. Why? How can I prevent it?
