I read more than once that this specific promo is so highly protected, it became unplayable in cars and several cd players. The Dutch owner of this promo, had the same problem when I asked him about it. He never listened to it.
If the promo contains older mixes/premasters of the Zeitgeist tracks, it would be a reason to open it, and check it out however! Make a tiny cut in the plastic cover just to let the cd out, and try to play it. I did that a few times with other cds I badly wanted to hear.
