Help to understand haw tag management work

[Tim Curtis]

Moode accumulates the Performer, Conductor and Artist into the Artist tag and displays these values as a comma separated list in the first line of each track in the track list. The Composer(s) if any are displayed on the second line.

What's a bit confusing to me is that your sample Album "Cartoon Darkness" only shows 1 artist tag in MusicBrainZ Picard.
