Quoted from 320Gigabytes:I wish Brendan Small would have done ALL the call-outs on Metallica. He's hilarious, and he has extensive experience doing voice acting for countless characters in television shows.
I am in the same boat as you though Gweem, and I've actually got the Metallica code on my desktop because I was trying to change the music. Unfortunately I don't know anybody in my area with a Metallica to test it on.
I'm glad its the band doing the call-outs and not some professional voice dude. Its more authentic and you know is the band doing this, with there personalities mixed in. Yea, some are lame, but Ill take a few lame ones and have the band truly tied to the game.
