We had included native FLAC support in our Windows 10 expected features list, before Windows 10 for Phones was officially unveiled. Reason is quite simple, Windows 10 Desktop already has it and the underlying OS core being the same, we think it will be present in Windows 10 for Phones too.
@Lisan_09 Yes, FLAC support will be on phones/small tablets… won’t be in the first insider build, though, will be a few months later..
