If you previously downloaded the Death Magnetic song pack for the Xbox 360 or PS3 version, you'll also be able to play it with GH: Metallica. Meanwhile, those of you who buy the PS2 or Wii versions of GH: Metallica will get three songs from Magnetic - "Broken Beat & Scarred," "Cyanide" and "My Apocalypse" - on the game disc itself to compensate for the lack of DLC support. The game will ship for Xbox 360 and PS3 on March 29th and is expected in early May for PS2 and Wii.
