Artwork has been working for me....for the most part. The strange thing is that artwork doesn't show up while a track is playing, regardless of whether or not it is downloaded. If I go back or forward a track and then back to the one I was listening to before, the artwork is there....kind of a moot issue at that point - I'd like the artwork to show while the song is playing. It's clear that the artwork is downloading while the song is playing, so why doesn't it show up as soon as it is available? iOS flaw, or iTunes Match once again buckling under the pressure of server load? Songs themselves seem to download fast enough, so I'd think the couple of KB file for the artwork would be pretty instant.
