The Disney/Nickelodeon girls just aren't album sellers. My Everything selling 1.65M total with all of the hits, radio airplay, award show performances, televised appearances, media exposure, online discounts, commercials, and God knows what else attached to it is more than enough proof.
Aside from teenaged girls and a handful of gays (both demographics that aren't exactly known to be album buyers), who else is going to be seen purchasing a Selena Gomez or Ariana Grande album?
