What song had the traditional childrens taunt in the chorus?

Hi,

I am trying to find a song, the part of it I remember is I think the chorus, which is like a choir of children singing "na na na na na".

I think it was by a rap artist, somone like Eminem but I cant be sure.

Thanks.

It may be like toy soldiers by Eminem
