Rockbox

I think Rockbox should use sorting tags, if present, to sort artists, albums, and tracks. This allows a graceful solution to the perennial question “What do I do to make Bob Dylan sort under ‘D’?”

The ID3 and Ogg Vorbis tags that supply this information are listed below. There may be others for other tagging formats.

ID3 Ogg Vorbis

TSOP ARTISTSORT
TSOA ALBUMSORT
TSOT TITLESORT

EXAMPLE 1: A file contains the tags ARTIST=Bob Dylan and ARTISTSORT=Dylan, Bob. The ARTIST tag is used for all display purposes, but the ARTISTSORT tag is used for listing artists.
EXAMPLE 2: A file contains the tag ARTIST=Grateful Dead but has no ARTISTSORT tag. The ARTIST tag is then used for both display and sorting.

The ARTISTSORT tag would be the highest-value addition to Rockbox, but ALBUMSORT and TITLESORT have potential value to users as well, such as sorting albums by date.
