Previously, we queried for the extra view's stats during the rebuild.
The full rebuild can take an arduous amount of time. By moving the
background calculation outside of the rebuild code path, we can
load the stats in the background and update the view outside of the
app loading cycle.

When you tap the Music & Audio preference, it takes you a
hybridized applications view. In this view, there also is
a line item which defines the amount of storage used by
audio files on the device. Using the new storage query, we
can add this information very quickly to the view.
