Re: wikipedia...
to the best of my knowledge, HC is about 12x platinum (12 mil) in the US, and MOP and Weathered are in the neighborhood of 6x. Greatest Hits isn't anywhere near that, so, in the US alone, that puts them under 30 million. Worldwide, I can't imagine them having sold 20+ million between Australia, Japan, UK, Germany, South America, etc....
Also, Wikipedia isn't a reliable source b/c anyone can edit it. I'm sure it's possible someone disliked Creed enough that they edited 'em from the list themselves, but I'm really not sure if they did sell 50 million total.
