I am new to iTunes Match and I had ripped some CDs, the ripping was great and the tags are alright, but the artist name was 'various artists' instead of Rihanna, Madonna etc. I changed that, so that it would look right on the iPad. I used an iMac for ripping and modifying tags. I had already matched them with iTunes Match. I thought it would work the way that, after having clicked "Update iTunes Match" in the menu, it would refresh all tags. Doesn't it work this way?
Do I have to intervene before the first matching? Huh?
