Instead of a count, I'm going to include a multiple choice poll with some of her biggest hits (as a lead artist). Less obvious options aren't going in the poll, but feel free to name something that's not here.
That makes total sense, I mean it's not like she has the most hits and #1s out of all the girls in her generation or anything
Rihanna has had so many hits in such a short time that a lot of them are going to be forgotten; that's just how it works. She's not a longevity-driven artist.
