When enabling artist / album / track translations the locale selection sometimes gives unexpected results.

1. For album and track titles a non-primary alias is used instead of the primary one for the locale
2. If there is no exact match for the preferred root locale, but a full locale would be available, a secondary preferred locale might be used.

 

E.g. you have preferred locales en, de (that is prefer English over German), but the entity has aliases only for en_US and de.

Currently the logic would not match en_US (because it does not exactly match), but de (because there is an exact match).

This seems unexpected. The user wants English first, so it should prefer en_US if there is no exact match for "en".
