i think it gets called a flop a lot because it failed to reach platinum status and fell from the charts quickly. also, beyonce's album came out later and without promotion, so i wouldn't use that as something to compare artpop to, which recevied heavy promotion and came out earlier
While Gaga isn’t performing up to her previous album numbers, in comparison to these other two albums numbers that are considered “successful”, Artpop certainly isn’t showing the dismal numbers that washed-up has-beens like that “complicated" rocker (trying to keep a straight face typing that) chick are generating.
BTW, I’m not a “Little Monster”. Just think that a flop should be, actually, a genuine flop before it takes away from Kween and her hard-won accomplishments on the charts.
