If you picked up Rock Band 3 but miss some of the classic jams from Rock Band 2, you are covered. You can bring (most of) your favorite songs into RB3.
Its a relatively simple process. just find the code on the back of your Rock Band 2 instruction booklet. Start up RB3 and select “Get more songs” from the menu. From there you should see “Redeem code.” Enter your code and you are done.
It should be noted that there is a $9.99 licensing fee to rain on your rock parade. There are a few omissions that couldn’t make it to the tour bus on time also. Not included in the transfer are:
* “Let There Be Rock” by AC/DC
* “Any Way You Want It” by Journey
* “Battery” by Metallica
* “Give It Away” by Red Hot Chili Peppers
* “Spoonman” by Soundgarden
Also the Harmonix band songs are not included but maybe available as a free DLC later.
