Consider the following track list, from this release, where the work title is in English, but the movement names are the typical Italian.
I have always treated releases like this as an English-language track list, regardless of the movement names, and so I would set the release language is “English.” In my experience, I think most editors of classical releases do pretty much the same. But I can find no guideline or discussion that confirms that this is the way it should be.
There is an open edit on this particular release right now, changing the language to [multiple languages]. My instinct is that this should be English, but, with no clear guideline, I don’t know if I’m justified to vote ‘No.’
