Question re track titles:
When a release has titles in several languages (for example, English / German / French), enter the tracklist in the main language of the release. If all languages are given equal weight, just pick one. The others can be entered as pseudo-releases and linked to the release marked as official with the appropriate relationship.
However, this one: https://www.hyperion-records.co.uk/notes/67895-B.pdf seems to indicate to me that both languages should be included in the title. The booklet has the Czech title in italics. How to show this? ‘English - Czech’? ‘English (Czech)’? ‘Czech (English)’. If I omit the Czech it will be lost entirely (as the works are entered in English, rather than Czech with English alias).
