Ok, so I have all my MP3s loaded onto the empeg. They're arranged in hierarchical playlists in the format \Type\Artist\Album\Tracks.
For some artists I have entire albums, plus some extra tracks. I've put the extra tracks in the Artist directory, so we also have \Type\Artist\Tracks.
When I go into the \Type\Artist\ playlist, I see the play icon, then all my Albums, then the music icon. The play icon will start a temp playlist of all songs by this artist. Good - that's what I expect.
The music icon refers to the tracks that are not in an Album playlist. Selecting it shows another play icon and these tracks only. So far, so good. However, selecting the play icon at this point does not play only these tracks, but instead plays all tracks by this artist.
In other words, the play icon here is inconsistent with its behavior earlier. Since there is a list of tracks shown at this point, it should play only these, not every track by this artist. It seems to be a sub-selection problem.
