I don't really believe it. I thought it was at 2.5-3.5 million.
Me neither. It sold 963,000 in the US and I don't think it sold another 5 million in the rest of the world, especially when it only charted in the US at #28.
obviously, it didn't sell 6 millions. this looks like a desperate attempt to make her look successful. The album is not even a huge catalog seller. labels always inflate sales like this.
