If you're one of those completists who felt Best Buy's blue fist closing around your wallet when Ubisoft announced exclusive songs for people who purchased Jam Sessions through the electronics retail giant, allay your fears!

It turns out that all you need to do to unlock the three bonus songs is enter a shortened version of the Konami code while in Free mode: Up, Up, Down, Down, Left, Right, Left, and Right. Those of you who've set the game up with left-handed controls should be able to enter the sequence with the ABXY buttons: X, X, B, B, Y, A, Y, and A.

The three extra tracks, in case you've forgotten, are the following:

• Brad Paisley - "I'm Gonna Miss Her"
• Jimi Hendrix - "Wild Thing"
• Tom Petty - "Needles and Pins"

Speaking of hidden stuff, the murmur amongst murmuring folks seems to be an eerie message in Jam Sessions when you hit the A6 chord and hold it out. After a few seconds, you can hear what sounds like someone whispering, "Don't kill us." Other interpretations of the barely audible voice include "Forgive us" and "Oh god, this is sooooo creepy. What the hell, guys. What. The hell. Seriously ya'll, quit messin' around, this ain't a game. Let's get out of here and eat pizza rolls at my place."

Check past the post break for video and audio proof of the spine-tingling whisper. We guarantee that your spine will be tingled!
