Ok. I have the grand daddy of all stumpers. Here is the situation. I “created” the LinkinPark Greatest Hits Album called Papercuts using the original albums. I updated the titles, album, etc date. I then updated the ITUNES ratingadvisory, albumID, artistID and catalogID all to be consistent with Papercuts. The album artwork renders correctly on my Mac, iPhone and IPad. However, it my car’s infotainment center if renders the original albums (not Papercut). Anyone have a solution for this? ITS A TOUGH ONE
See e.g. this thread about a car system that uses its own database:
you would have to find out what your system does.
