I noticed today that tracks from 'various artist' albums are displayed differently in Playlists than they are in their album view.
In the id3 tags for these tracks, I have the Album Artist as 'various artists,' and the Artist as the individual performer of that track.

When viewing a 'various artists' album in Plex/Web, each track is displayed with the Artist tag next to it:

But when you add these tracks to a Playlist, they are listed with the Album Artist tag:

It would be much more useful if the Playlist displayed the Artist tag rather than the Album Artist tag. This would follow for any apps that support playlists as well, such as the Roku Prevew app.
