Cobra Starship's new single, "Good Girls Go Bad," features none other than Gossip Girl's Leighton Meester chiming in on the hook. I have to admit, I'm pretty impressed with her voice. She also stars in the video for the single (see above). I think this song is ridiculously catchy...some blogs are calling it the "song of the summer." What do you think? Catchy or annoying?
