According to the US Singles Top 40 list, Ariana Grande's 'Problem' and Iggy Azalea's 'Fancy' are the #1 and #2 song in the country. Which one do you like better?

I have definitely become a big time Iggy Azalea fan, especially after doing the FUN Morning Lip Dubwith Michael Rock, and Loren so I'm torn right down the middle.

What do you think?
