Yes It is. What pop song can people name that's better than it? Critics agree it was the best pop song of 2011, so what released in 2010 & 2012 is better than it O.O
I was originally gonna say that it's in the top ten... but now that I think about it, I honestly can't name any better pop songs released in the '10s. So yes, it is the best pop single of the decade.
