I'm looking for a version of the Stage 5 final boss BMG that isn't on the two soundtracks on the main GH site. It's in the background of http://www.youtube.com/watch?v=nscP9QpXoFM. Help with this would be most appreciated.

Scary... I was about to post this myself

And it looks like I found it... I found it in the shmup music thread: http://www.megaupload.com/?d=QW2SW54F
