Okay, so it says promotion, do you think its promotion?
So,
Rihanna is promoting long mess of eras by reposting/posting/commenting/liking **** on instagram?
I think Rihanna has everyone beat then, she clearly does the most promotion.
Hun, your fellow monster called it promotion. Even If you don't go by that list, Gaga has performed MTN more than Rihanna promoted the whole UA era. Stop denying that.
I would make a list similar to that for Katy, Rihanna, Beyonce and Britney..
But half of them wouldn't be able to land all that "promotion" overseas, it would be virtually impossible to determine when and era ends and begins for one of them, and the other is dead.
