Rather than have a circular debate about which should be adopted, and avoid knee jerk reactions similar to my opening post, I thought it may best be approached by reference to other apps, software or standards.
Current software approach
ITunes, Jriver and Roon are some of the major media servers that I am aware of. I do not use them but I believe they lean towards, or at least provide an override to, ignoring articles. Another media server, I do use, Minimserver provides an override to ignore articles. Auralic Lightning server also provides an option to ignore articles
Linn Kinsky, Lumin, mconnect and BubbleDS next do not ignore articles and do not provide overrides. However, they are control points and are provided with appropriate sorted/indexed music tracks by the selected media server.
Perhaps this is a compelling argument to suggest that it is the media server that controls the sort/index preference.
I have chosen the following.
Guidelines for indexes and related information retrieval devices.
Guidelines for alphabetical arrangement of letters and sorting of numerals and other symbols
The Foreword of the latter contains this paragraph.
"Virtually all alphanumeric headings today are arranged by computers, not by human beings. However, before headings that are to be arranged by an exception to a rule can be sorted automatically, intervention by human beings who can use criteria other than the sequence of letters or numerals is needed."
This is further expressed by the section "4.6 Headings Beginning with Articles"
Perhaps, again, this is an argument for the user to intervene and apply their criteria via overrides provided by media server or control point.
The ISO Standard on indexing section "6.2.5 Articles" states.
"Initial articles should not be omitted from names of persons, places or corporate bodies or from titles."
For corporate bodies, substitute artist band/group names and titles (album and song).
Again, let the user intervene and apply their criteria.
Phew! I think I need to go and lay down.
