Gotcha. Thanks! I thought I read somewhere that it would, must have been wrong.You're not doing anything wrong. iTunes Match will not replace your metadata, even if you delete a song and download it from the cloud.
You could try to use some tagging software to fix your metadata.
That is a good question. I am ANAL about my artwork and only like to use hi-res scans...so my artwork is pretty top notch and solid. Well AFTER iTunes Match I had to go back through almost every single one of my albums and re-download the artwork. This is not a common problem, but it has happened to others.Gotcha. Thanks! I thought I read somewhere that it would, must have been wrong.
So it doesn't update the artwork either?
