[Delulu Rogers 6,491]

Alejandro slayed all of Europe (especially Southern Europe) when it came out. It's probably on the same level as poker face and bad romance there. Judas was pretty big too

Alejandro, definitely

[LDGA 1,260]

Alejandro, i still remember that song as the only song gaga’s song that i have heard on the radio of mi city.

I was living in Brazil during Alejandro and even my grandfather was singing it!

[ObezyankaNol 2,979]

My parents know Alejandro's chorus, so I would say Alejandro. Even my dad that doesn't know anything about Gaga's music sings Alejandro, Fernando, Roberto 

It was a big hit here in Argentina. I miss those days 

[DiscoHeaven23 35,007]

DWUW, Canada loved it

[BeIIadonna 5,480]

Bad Romance?

What answer did you want? G.U.Y?  

[Miaou 39,013]

It's between Telephone, Paparazzi or Alejandro but I would say Telephone because of the enormous impact of the music video.

ummm since you excluded BR, I think it is Telephone, it was pretty popular in Hong Kong during that year.
