Here is some useless but (possibly) interesting information: In the ancient days of iTunes the ignoring of articles was controlled by a "SortPrefixes" file that was pre-popped according to language: a, an, the in English; le, la, les in French, etc. Here is an old post on the topic: https://discussions.apple.com/thread/2302477?answerId=10916630022#10916630022
You could edit it if you wanted to change the behavior, but that could lead to odd behavior, e.g. if you wanted Die Walküre under W, you were going to get Die From a Broken Heart under F.
Use of the Sort fields gives much better control. Downside is it doesn't lend itself so well to mass changes, but hey, that is where scripting comes in.
