The 18-song Walmart exclusive AC/DC Live: Rock Band Track Pack, which went out a year ago, will be available at GameStop beginning next month, and for less than the disc's original full price.
GameStop lists it for shipment Nov. 4 at $19.99 - of course, less than the $29.99 to $39.99 it sold for when it debuted a year ago. The tracks can be transferred to your hard drive for Rock Band or Rock Band 2, but just for the 360 and PS3 version; not the PS2 or Wii.
