When browsing by artist or album it is not uncommon for users to be presented with a list of several hundreds or thousand entries.

The web interface provides a convenient method to jump to the desired location in the list by selecting the first letter of the artist or album.  The controller has no similar option and instead relies upon scrolling up or down until the desired entry is reached.

I propose to change the controller interface such that when the user selects, for example, to browse by artist they will be presented with the following type of display:

******************************
[Filter]
[Jump to...]
10,000 Maniacs
10 cc
.38 Special
A Flock of Seagulls
Abba
Al Stewart
Aerosmith
.
.
.
ZZ Top
******************************


By selecting either [Filter] or [Jump to...] they will then see the following:

******************************
[123..]
[A]
[B]
.
.
.
[Z]
******************************

Had they previously selected [Filter], if they now selected [B] they would be shown only those artists which began with the letter 'B' from which they could scroll up or down and select as desired.

--Optionally, from this screen the user could further filter on a second and successive letters.

If they had chosen [Jump to...] and then [B], the entire artist list would be presented but they would be placed at the first artist which began with the letter 'B'.  Scrolling up would take them into the A's and scrolling down would lead to the rest of the B's and eventually to C and beyond.

Similar behavior would be available for browsing by album.
