If you picked up a copy of Rock Band 2, you might have noticed that little code in the back of the instruction manual where you can get 20 free songs. Until now, it’s been a mystery as to just what you’d get. But wonder no longer, my friends. Here’s all the songs in their glory:

• The 88 – “Sons and Daughters”
• Authority Zero – “No Regrets”
• Between the Buried and Me – “Prequel To The Sequel”
• The Cab – “Bounce”
• The Chevelles – “Get It On”
• The Cocktail Slippers – “Give It To Me”
• Dealership – “Database Corrupted”
• Endeverafter – “I Wanna Be Your Man”
• The Ghost Hounds – “Ashes To Fire”
• Hollywood Undead – “Young”
• Kutless – “The Feeling”
• The Len Price 3 – “If I Ain’t Got You”
• Lesley Roy – “I’m Gone, I’m Going”
• Opiate for the Masses – “Burn You Down”
• Semi-Precious Weapons – “Magnetic Baby”
• Shaimus – “Like a Fool”
• Thenewno2″ – Crazy Tuesday”
• Tickle Me Pink – “The Time Is Wrong”
• Underoath – “Desperate Times, Desperate Measures”
• X Japan – “I.V.”

Not a terrific list, but it’s not bad either. You can’t complain for free content, so don’t try. Make sure to enter your code over at the registration site and wait for November 4th when these songs will be available for download. And if you haven’t gotten Rock Band 2 yet, what are you waiting for?
