Sorting by artist's last name in Apple Music

Hi there,

I have quite a large music library in iTunes Match. I have spent many hours over the years, sorting my library in the "proper" way - by an artist's last name. Now, with Apple Music, whenever I add a new album by an artist already existing in my library, the app re-sorts the artist's music to appear by its first name (for instance "David Bowie" used to appear on B, and now he appears on D). I tried to change the sorting fields on iTunes, but to no avail - If I change the "sort by" field to "Bowie, David", it would also change the artist's name field to "Bowie, David".

Any ideas?

Thanks,

Joe
