Gossip Girl vs. Game Geek: Who will win?

So Kongye didn't specifically mention this, but as stated in the second clip they uploaded, Serena and Vanessa compete with each other while playing Guitar Hero II on an Xbox 360. Serena apparently racks up an unbelievably high score on Freebird. Vanessa responds that Freebird is nothing and she's about to blow Serena away with her performance on Cherry Pie.

There's just one problem with this statement: On a difficulty scale of 1 to 8, with 8 being the hardest, Cherry Pie ranks as a 2 in Guitar Hero II. By contrast, Freebird is the hardest fucking song in the entire game.

Considering that pretty much anybody who's ever played Guitar Hero II would know this and that's pretty much the majority of their demographic right there, I honestly wonder who they thought they were fooling with that scene.
