The new full Metallica album "Death Magnetic" is available for download/purchase on Guitar Hero 3, XBox Live marketplace.  They have also added about 10 or so Music Videos for download/purchase.  I do not own a PS3, so I am unsure if it is available on PSN, thats why this is posted in the MS discussion.  Regardless, its kinda cool to have a full new Metallica album to play on Guitar Hero 3, until the full, Guitar Hero Metallica is released. 

Just thought I would share the info.  The album is actually pretty decent......my opinion of course.  Check out a few reviews on Metacritic if you are curious.

Album is a lot better than most recent Metallica imo. Glad to see that it's usable in GH3 and GH:WT.

Buying the music videos on XBLM is kinda a ripoff tho imo =/
