No More Metal in Guitar Hero/Rock Band?

So today I was litening to some Lamb of God, and I got to thinking to myself, have we seen the last of any really good metal songs in Guitar Hero and Rock Band?

I was thinking, now that we have singing in both games (a feature I could easily do without... but I realize it kind of adds to the whole "band" thing), will we ever have any more true metal songs like Six, My Curse, Take This Life, and The Light That Blinds? I mean, it will probably be fairly hard to pull off metal/growling vocals in these games well enough to not be lame. Even these songs are fairly tame as far as lyrical stylings. You may point out that they are making a Guitar Hero devoted entirely to Metallica, but they are much more of a "singing" band, and the vocals aren't hard to pull off. In GH:World Tour and Rock Band 2, we are seeing very little metal songs, aside from Metallica. I wonder why exactly this is, but I have a suspicion the vocals are a pretty decent-sized factor.

Also, the drum parts would probably also be especially hard. You have some pretty heavy double bass in a lot of modern meal songs, and only one pedal to work with. The beat would probably throw you off, since there would be no real way to match it perfectly.

Then, I remembered that Korn's "Freak on a Leash" is in Guitar Hero World Tour. If you don't know, this song has this one part that's like growling scat vocals. I was like hmmmm, I wonder how they pulled this off. Well, the results can be seen below, at around 2:55:



Hmmm. Not sure how I feel about that. The video quality is terrible, but it seems like he is hitting the "notes" for the most part. I wonder if its the same for a female trying to do this, without the deep tone. Meghan will have to try :) .

Anyway, this isn't quite the same as a true metal song/vocals. And the intrument parts are not hard at all for the song. Hopefully, we'll see some downloadable content for these games with some actual metal in them.
