Yes, I'm still thinking about Ariana Grande's fame level, and I think it's this: the average person would be able to summon a mental picture if you said Grande's name to her, but getting that average person to guess her name based on a series of facts about Grande would be much harder. I read the entire internet every day and I know the title of one of her songs (and I even had to google it to make sure I was remembering right). So if I were challenged to name four things about Ariana Grande, I'd go, "Pop star, ponytail, kitty ear headband...'Problem'?" But even if I gave those clues to a random adult walking down the street, I bet the success rate would be low.
