In the library explorer (when sorted by artist) one can see the number of different albums for the respective artist.
It's not actually showing the number of albums specifically - it's showing the number of items below each entry in the list, which may or may not be albums, depending on the
Sort By values you have selected.
For example, if I sort by
Genre, the number next to the artist name isn't the number of albums - it's the number of genres I have assigned to them:
(Also notice that it shows five album entries here, even though there are only four, because one of them has two genres.)
So the only way to have it show the number of tracks for each artist would be to add a custom sort entry using a field unique to each track - like URL - and apply that:
Now it will correctly show that there are 46 RATM tracks in my library, but because it displays the URL, below the
Artist level it is basically useless.
Other panels like the
Column Browser can show the number of tracks per
Artist though.
Bee excellent to each other...
