Xbox Evolved writes: "Make sure you read the title of this game very closely: "Track Pack". Although you must physically walk into Wal-mart (the only retailer of this game) and purchase the actual disc, this "game" is nothing more than a set of songs that should have been DLC from the Marketplace. After buying the game, you can enter in a one-time use code on the back of the manual to export the songs to your hard drive to play within Rock Band or Rock Band 2. Thus, if you like AC/DC, you absolutely want to buy this game right now. It contains 18 live versions of a band you love and you can't go wrong with that. Conversely, if you hate AC/DC, there is no chance you will enjoy this game."
