If it's one or the other I would much prefer to keep track count.
Album count only seems useful if a library consists of whole/complete albums because it really means "You have tracks from x different albums by this artist", regardless of whether you have every track from that album or not. This is a lot more ambiguous than "You have x tracks by this artist". I have a lot of albums where I have only one or two tracks, not to mention a lot of singles, so for my library at least album count would be a pretty meaningless number.
Does a track on a mixed artist compilations count toward that artist's album count? If not, how do you exclude it from the total?

Bee excellent to each other...
