After that, a three-pack of Green Day songs will comprise part of the downloadable content for the week of December 14 on all three platforms, again for $2 (160 MS Points, 200 Wii Points) apiece and in a track pack for $5.49 (440 MS Points) on 360 and PS3.

Green Day Track Pack 2
• Green Day - "Christian's Inferno"

"Viva La Gloria!" and "Last of the American Girls" will also head to the family-friendly LEGO Rock Band store, while "Christian's Inferno" is apparently inappropriate.
