It wont be anytime soon, but its possible.

You should also look at it from a cultural perspective. Hung Up hit no1 even in countries where you barely see foreign songs in the top5. Most of the hits you have mentioned above were very big mostly in English speaking countries. Hung Up and the Confessions era literally penetrated every culture and nation of the developed world.

Because 'Hung Up' was "mature enough" for a 47 yo popstar dancing in a pink leotard in front of a mirror, going out and kissing random guys in a club.

Rolling In The Deep.

Not yet

Her label says 35 countries.

RITD is clearly the bigger hit. The song was still strong in the first part of 2012.

'Poker Face' had very strong catalog sales, too. It sold 2M in the US alone after 2009. 'Rolling In The Deep' may overtake it eventually, but I'd say 'Poker Face' still has the edge at the moment.

The Baby One More Time numbers posted above are NOT accurate! They count as a no1 no1s on
"international music" charts that every country has. It might have hit no1 on the chart of international songs in Turkey, Venezuela, Greece, Chile etc but it might have peaked only at no9 on the overall singles chart. Baby One More Time did not hit no1 in more than 20-25 countries. 20 countries is still extremely big.

Hung Up's no1s are totally real. No1s on the official charts of every country with domestic music included. Not just international hits. That's what makes it extremely impressive, shocking and iconic. And it happened in 2005/2006... 22-23 years after her first hits... Insane...

Didnt On The Floor hit #1 over 23-24 countries?

Yes it was very big!
