Ever since iTunes Match came out, it's had issues with syncing metadata like "Grouping" from devices back to iTunes. So for example, on iTunes, I'd have a smart playlist with the condition "if Grouping contains: happy". But when it'd sync with my iPad via iTunes Match, the smart playlist would completely disregard that condition. I also noticed in the past that Play Counts would never sync from my device to my iTunes. Well, I've done a little bit of testing and it looks like iTunes Match is properly syncing Play Counts and other metadata! Can anyone else confirm this??
