It is.
ARTPOP was messy but didn't flopped, it was a underperformance. And Applause was top 10, DWUW went platinum, G.U.Y. had a great video (despite the flop), the era had a tour, etc.
Britney Jean is not even considered an iconic flop since no one remembers/cares for it, not even Britney. It was a buzz promotional album for her Vegas residency.
No one expect great sales for Madonna nowadays, only some of her delusional fans, so her flop is not even surprising at this point.
Bionic was a mess. She came from a successful era but everything went wrong.
0 hits, 0 top 10s, no tour, completely low sales in general and for her standards, the never ending Gaga comparisons, only 2 music videos... and i think this era started the new "flop" trend era on online forums tbh.
It's a shame since BiConic is my favorite Legend X album and deserved way more. The album still sounds fresh today and it's full of bops. I bought it the other day on a physical store and i had a mini meltdown when i saw it cuz it's been a while that i was trying to get my copy, now i own it. The booklet is flawless, so is the album.
