I like the 7 or so GNR songs I have heard from Chinese Dem.
As for Metallica, I have it on pre order for free from amazon.com thanks to a b-day gift card.
I don't like the argument that people should stick with a band if they determine they no longer like the music the band is putting out.
There are tons of killer metal bands in all the various metal genres. I don't owe my loyalty to any one band. Cd's cost too much money. It is cool for them to put out any type of music they want and I have the right to buy or not buy it.
