Saw IV

[Showren]

(I searched and found no threads for this yet... I'm a little surprised) Anyway I have reading all over online that X-Japan (a japanese hair metal band) wrote a song called I.V. to be the theme for Saw IV, the company that made Saw IV also did Catacombs with Pink, in which Yoshiki (the drummer of X-Japan). Is their anyone who has seen the movie that can confirm this...? I'm just curious, it would be an interesting way to break into the U.S. music industry, through film, reminds me of Drowning Pool a little bit.
