BTW sold that much in less than a year. Other, after 2 years of its release, needed a re-release to get close (couldn't even pass it ) of BTW's numbers.
BTW Ball Tour grossing alone puts this others albums on the floor.
Plus, isn't it a fan run site? Sure, it's nice for a quick reference, but those saying we should believe a fan site over Billboard are entirely incorrect.
Yes, it's a fan run site. But they are the only ones who count weekly about the sales. And be careful, because Billboard does count the albums distributed to the stores ._.
