I knew I would forget to mention something. At the moment the only artist artwork that can be pulled up from an album or song ListItem is the fanart, and no album artwork is available from a song ListItem if the song has any of its own artwork (like a thumb/cover). Ditto "Player.Art" for now playing music. Dave is working on that, but in the meantime all artist and album artwork is available on MyMusicNav and DialogMusicInfo from the container as "Container.Art(artist.clearlogo)", if it's not a playlist or other mixed list.
