Music.app on iOS: use a different language other than the system language? As explained in the title, I want to use Music.app in a different language other than the system language. 

However, unlike many other apps, it doesn't offer such an option in settings.

I'm wondering if it is possible to do so by tweaking appropriate plist files. If so, how?
Sadly, no - there’s no published setting to make this edit for Apple’s app. That doesn’t mean it’s not possible, just that it’s unknown. 

Applying pressure to Apple for this may or may not be effective, and hopefully someone can document this and make my answer wrong or in need of an edit to explain how.
