So with that mistake cleared up, to people wondering about the gap between All of Me/Problem last week:
Problem would actually have needed to sell about 12k more to get #1, not 1k or whatever people thought.
follow-up "Birthday," meanwhile, jumps 29-25, led by its 34-22 vault on Radio Songs (46 million, up 20 percent) and No. 42 debut on Digital Songs (38 million, up 20 percent).
Wait so Birthday now is the best selling single of all time?
The bottom half of the top ten is so weak right now, so I would say closer to 25 is possible.
She will break her personal record in two weeks. ET spent the longest in the top ten (20 wks).
She will be one away from Taylor's # of 8-month charters.
However, Taylor has three 11-month charters, while Katy hasn't gotten a 10-month one yet, so her longevity isn't quite there yet.
YASSSSSS Paramore slayyyyyyy my favorite song ever! I'm so happy for them! Literally crying tears of joy! I cannot believe "Ain't It Fun" is top 10! ahhhh!
Finally, this is divine justice.
