Global phenomenon

She's selling on average 50K weekly based on Mediatraffic. There's around 40 weeks left in the year and not counting holiday boosts or seasonal boosts, she can add another 2M this year or so.

9.9 milion for Roar in 4 months?

Well done Katy

SLAY I guess

Wow almost 10 m in 2013 And Roar is still selling well around the globe in 2014.
It is coming for 15 million at the end.
I think Dark Horse will be big too, regarding its sales now, over 4 million in US alone. Dark Horse is highly charting around the world. It will be her another 10 m seller and end up over 6 million in US.

So Katy has the best-selling female album last year?

I mean, what kind of slayage from a local and singles artist?

PRISM sold less than 15k last week. Kinda flopping compared to TD's longevity.

What, Roar sold 9.9 million already?

BIRTHSLAY is coming to save that album sales!

Wait Birthday is the next single?
Anything as long as she doesn't release TIHWD.

2.8 is shipped numbers though right?

Ballads sell albums. Katy hasn't promoted a slow ballad yet this era (unconditionally wasn't really slow and impactful).

She can't keep putting out the obvious hits. She can stay album gems. BTGOG (with redone chorus) or ITT would get the album a lot more sales than Birthday even if Birthday was 10 week #1

The album should be well past 3 million by now.
