there's a stan war between Ariana and Meghan during that time.. with Meghan scoring no.1 and pure sales etc.. it's crazy to think that Ari didn't sell albums as big as TITLE or Billie's WWAFA,WDWG or SOUR
that said, TITLE demolished every ex-act's biggest Era (Demi, Selena, Miley).. in the US at least for Ari.. as ME is bigger than TITLE globally
