Huge old school Metallica fan here, and I at least like "The Day That Never Comes" which does have an old school Metallica feel to it. Especially the beginning, it reminds me of "Fade To Black". I need to listen to Death Magnetic more before I judge it. I listened to it once through, didn't care for it, but sometimes albums need to be listened to many times before you like it. After hearing "The Day That Never Comes" a couple times over, I like that song alot.
I like that they're bringing this thing out, but I don't really care for Guitar Hero. I wish it would've come out for Rock Band. I just like the feel of Rock Band over Guitar Hero. That being said, I'll probably still buy this thing. Master Of Puppets rocks.....
