I have three computers and I am using iTunes Match.
The first computer has 100% of the music on it local hard drive and it is synced to iTunes Match (total of about 9300 songs).
The next computer has maybe 20% of my music on it local hard drive and it is also synced to iTunes Match.
The final system is a Mac Air and it has NO music on it local but is also synced to iTunes Match.
I have a smart playlist that displays songs that do NOT have album art.
On the computer that has 100% of the music on it I have ensured that every song has album art. I have added art manually when required. So on this computer the Smart Playlist says 0 songs. (Every song has art)
On the PC that has 20% of the music on it the same smart playlist says about 200 songs do not have art.
On the Mac Air it says 400 songs do not have art.
Anyone have any idea how I can fix this?
I have gone to each system re-botted and resynced with iTunes Match just to make sure. But I still get the same result.
I have the latest version of iTunes on all systems.
I have found a solution...
The first issue is you have to know what songs are missing art and you need to have that list of songs on the machine that is NOT missing art.
On the computer that shows the MOST album art missing make a smart playlist that will display songs where album art is false. Then make a standard playlist on the same computer and drag all the songs from the smart playlist to that new standard playlist.
Now you have created a standard static playlist that shows all the songs that it is having issues with album art that you can view on the computer that has art.
On the computer that had the most album art correct (hopefully for you that one is a MAC) if you install this script http://dougscripts.com/itunes/scripts/ss.php?sp=reembedartwork from Doug's iTunes scripts.
And then run the script on all the songs in the newly created playlist.
NOTE: The script will fail if the song has NO album art on the computer your using so make sure you have manually fixed the few remaining songs without art. For me this computer has 100% of the art so it was not an issue.
This script takes each mp3 out of iTunes embeds the image within it and then puts it back with all the same tags and keeps it in all the playlists. This process caused iTunes Match to re-sync the song and the album art on all songs started showing again on all computers.
Having the images embedded in the mp3 is important I guess for iTunes Match.
