Localization top 10 languages to increase VR sales

Hi,

This is my first post in this nice community.

We are planning to release our first video app container really soon. "VR Horror Stories" main language is English even if 90% of the video app has no dialog. The VR experience is mostly happening in dark environments with creepy spatialized 3D sound. We decided to limit the subtitles to 6 extra languages. Does anybody has any recommendations as which extra language subtitle  would be best to use?  Any input would be greatly appreciated.  Thank you for your valuable input!
