Right now there's an option to show a vertical panel in the artwork view that lists the tracks in the album.
But, in case you're in the artwork view, you still know the album and the artist, so what you want really to know is the list of tracks, or perhaps a combined field that shows the artist if this is different from the album artist.
Anyway, why not giving the chance to show this panel vertically?
