Pretty Hurts will win the video for best social message. It had major impacTUHHH at the time of its release.
The only reason it flopped (we've been over this) is because the song and video were 7 months old when they were supposed to be brand new. People weren't requesting it on the radio because they were at that point, where you've had an album for 6 months, and you've listened to it so much, that you start to get sick of it.
