Not really the most global hit seeing as there is only a small number of artists included in this
Considering it was the biggest pop artists in the World, I would say it was. You do realise that 'Pop' is short for 'Popular', as in Popular Music, right?
1) Out of all the songs, Pokerface is the song that went #1 in the most countries (17 out of 19)
2) Pokerface is the only song on this list which has both topped the annual IFPI list & the Mediatraffic Year End chart, beating out the massive "I Gotta Feeling"
3) Pokerface is one of the 6 songs that went top 10 in all 19 countries analyzed + scanned either gold or platinum in Japan. 3 of those 6 songs are Gaga's.
4) Pokerface, along with Born This Way, Girlfriend, Bleeding Love and We Belong Together, are the only songs that have gone Platinum in Japan on this list.
5) If you exclude collaborations, Gaga has had the most entries on this list (3)
I would've liked to have included countries from Latin America, Africa and Asia but fact is that most of the countries there don't even have decent charts or they're too recent so the receipts would be too messy. Accept the truth and move on
