help please. very hard song to find,,

[Leeboy]

Hi.

I heard this song for like 3 weeks ago, and I have tried searching for it, but it's too hard, because all the lyrics is like na na naa na na.. and so on. cant remember if they say something else...
But..
It's a girl/woman voice, saying na na naa na na....
It's techno.
The melody, or what you want to call it, is a well known, and maybe a bit old melody. But now in techno version.
.. It starts up with a bang.. a drum-kinda sound. Or one beat.. Dont know what to call it, and smoothly the girl begins saying na na ... and the other sound.. Can remeber if they starts before the girl.. I think they do..
Ya.. Its not very useful informations but thats all I got.
I really hope you have some ideas of what I mean, and hopefully the song too.

Have it good!
