http://www.billboard.com/charts/top-album-salesAs previously noted, Billboard changed their procedure for ranking albums on the top 200. If you want to compare NPP to previous Beach Boy and Brian Wilson works, the Billboard album sales chart would be a more appropriate comparative analysis. This chart is album sales only. I think what Billboard did is confusing at best by allowing streaming to count towards chart position. I guess they're just trying to stay with the times.
