For starters, RIhanna's album was out way before LG's. LG's sold a lot more at a much faster rate. Rihanna also had more hits/singles thus far. LG didn't release a typical pop single. Moreover, of course Beyonce would sale like she does because the media kisses her azz & she has the element of surprise going for her. Y'all will do anything to denounce someone's success.. Lastly, Beyonce's latest album was very polarizing. And she doesn't do any promo & she hasn't made any pop singles in quite a while, which would help her to sale more. So that's that.
