ok im sorry i dont have a lot of info on this song

Ok so i just saw Live free or die hard. And when you first meet the hacker, you hear a song thats sort of diery and basicly you hear the girl say "i wanna"(or i want to) and then she screams "DIEEEEEE". so can anyone identify this song?

you mean when McClane meets Farrell?

then it is

Flyleaf - I'm so sick

here, the video and song: YouTube - Flyleaf - "I'm So Sick"
