iTunes Match artwork reverting to old version
On my primary iTunes Mac, embedded artwork that I've changed since turning on iTunes Match reverts back to previous artwork. For example, if I have a 500 dpi cover artwork in a track that iTunes has matched, then today I go upgrade the artwork to a 1000 dpi version, the next time iTunes Match updates it will wipe out my 1000 dpi version and replace it with my old 500 dpi artwork. It is NOT grabbing the iTunes Store artwork, it is somehow recovering MY old artwork from the cloud.
I've tried DougScripts Re-Embed Artwork script - no luck. I've dried deleting artwork, updating iTunes Match, pasting in desired artwork, updating iTunes Match again - pulls back old unwanted artwork. The only solution I've found is to upgrade the artwork, drag the tracks out of iTunes before Match updates, delete the tracks from iTunes and iCloud, and finally drag the tracks back in to iTunes. iTunes Match appears to keep my new artwork from now on (so far at least!).
I REALLY wish there was a setting that says "Never mess with my artwork!" It's great that Match doesn't change my iTunes audio files unless I tell it to. Why in the world does it change my artwork?
