Given what See You Again's subject matter is, it's truly appropriate to snatch number one from Uptown as an homage to One Sweet Day. It will be close though.
I'm assuming the rest of the top 20 is this...
(songs in red are the ones we know about already)
11. Somebody (-1)
12. Shut Up And Dance (=)
13. Chains (+6)
14. Want To Want Me (+3)
15. Time of Our Lives (-4)
16. One Last Time (=)
17. Truffle Butter (-2)
18. Blank Space (-5)
19. B*tch Better Have My Money (+4)
20. Take Me To Church (-6)
If UF! can't snatch her 20 years later, I have no idea what could be able to at this point.
She outran Candle in the Wind which sold 3,000,000 in a single week and had 14 weeks @ #1.
She outran The Boy Is Mine the earth shattering female collaboration.
She outran We Belong Together, the 16 week airplay #1.
She outran I Gotta Feeling the biggest digital song ever.
She outran Blurred Lines the song that snatched her airplay record.
She outran Happy, the song in the T10 of Worldwide All-Time Chart on Unofficial World Chart.
Macarena, Harlem Shake, Boom Boom Pow, Lose Yourself, and Yeah! also tried to threaten her.
