Solved: Female vocal hip hop loop

While traveling i heard a song on the radio that sounded familiar, but I can't for the life of me seem to remember any of the lyrics, or the name the artist, of the song. It's been driving me crazy to the point that I'm actually losing sleep over it.

This is what I can rember about it:

-It's got a hip hop feel to it
-The intro is a female vocal loop
-The intro vocals are in the higher pitched range


In writing the vocals goes as follows:
(I'll try to illustrate the higher pitched "na's" by writing them in caps, hoping to get some sort sense of melody out of it).

"Na NA, na na, nananananananaNA" - looped for about 30-60 seconds in the intro.

I am fairly certain that this has been a semi-popular song since I know I've heard it before both on the radio and on the internet, so it's not completely obscure.

Does this ring a bell to anyone?

EDIT: Found it.

Hi I am trying to find this song too. Heard it at a grocery store. What's the title?

The one I looked for was "La La La - Naughty Boy, Sam Smith".
