I think sales are brought up because dragging someone for your faves talent is never ending. Bringing up sales receipts is easier to clock the tea and move on to the next.I really don't understand why people ever compare sales when having these little stan wars. Yes, because what's popular is automatically "better" than what's not as popular. I fail to see the logic. I mean look at Katy Perry.
EDIT: Phono has a point this era album sales are totally different from before lmao
