Of course there are exceptions, I'm just saying that title case is far less common.
First, as I said it's matter of taste, I don't think there's a 'right' answer, feel free to choose whatever for Rockbox.
But to answer your point, title case is more common in computing for menus and settings, an audio player is closer to a computer than a newspaper - ie. it really is a matter of taste, not nationality.
