Cobra Starship (feat. Leighton Meester)'s "Good Girls Go Bad" starts the beginning of Georgina's party scene as Dan escorts Blair into the party. This song may not be so much for Blair as it is for Georgina, who Dan apologizes to and offers a second chance at potential friendship. It's volume climaxes as Georgina and Dan continue talking, Blair looks increasing uncomfortable, and Vanessa avoids Blair with a look of disgust.
The second most played song of this Gossip Girl episode is "Hot Mess" by Cobra Starship. Who wouldn't love a song about girls' trashy behavior Russian escort and the guys that love it? This song is upbeat, the chorus is catchy, and the beat is goes pretty hard. This song fits Serena's train wreck of a life perfectly! We first hear it as we see Serena on a date with Carter Basin. They un-coincidentally run into Chuck during a business meeting, successfully ruining his dream of opening a speakeasy.
