Song? System of a down?

Question

What song is it? It's a hard rock band and it starts out "Ooh wa ah ah ah" by a guy's voice

That probably sounds really idiotic but that is all I remember of the song

I have a feeling it was on a commercial for Rock band or Guitar Hero..?

And maybe by System of a down..

Can anyone help me or does anyone have any idea what song this might be?
