How to use both English/localized and original artist name in path formats?

[ali-ramadhan]

Just started using beets yesterday (moving over from Picard) and loving it so far!

I'm still trying to set up the "perfect" config and was wondering if anyone knew of a good way to use both the English/localized album artist name as well as the non-English/original name in path formats.

So something like

$localized_albumartist ($non_localized_albumartist)
Kaori Kobayashi (小林香織)
Ziad Rahbani (زياد الرحباني)

It seems like you can probably not set the languages option in the config.yaml so that $albumartist gets populated with the original artist name then use $albumartist_sort for the English/localized name (if they're different) since it's usually in English

item_fields:
    bilingual_albumartist: u'%s' % (albumartist) if albumartist == albumartist_sort else u'%s (%s)' % (albumartist_sort, albumartist)

but this doesn't work well since $albumartist_sort is different sometimes (Kobayashi, Kaori or String Cheese Incident, The for example).

Sorry if I'm doing this awkwardly but any suggestions/recommendations would be appreciated!

This feels doable. It might be useful to write out explicitly how you expect certain situations to be handled. These could eventually become test cases. Ex:

EN name, no JP name
JP name, no EN name
both names
neither name
RTL text

I find this code a bit unreadable, would be better with some line breaks and more explicit if/elses, especially during planning/feedback.

bilingual_albumartist: u'%s' % (albumartist) if albumartist == albumartist_sort else u'%s (%s)' % (albumartist_sort, albumartist)

You might need some way to define the canonical / native name. Not sure how MB does it.

If MB doesn't provide it directly, could map country of origin / area to the language spoken there.
