Use Case:

1.  Navigate into am artist beyond the initial list of artists (non bolded letter)
2.  Select and artist so the display shows the albums for that artist.
3.  Select Artist from the navigation links above the album list
4.  User is directed to the beginning of the artist list.

The enhancement would (in step 4) to bring the user to where they were in the artist list when they selected a particular artist.

The same thing happens for Album navigation.
