Panic! At the Disco have posted the first song from their as–yet untitled full length. The record is due out March 25, 2008. It is the follow–up to A Fever You Can't Sweat Out which was released in 2005.

The track represents a rough mix and is expected to "undergo some changes" in the coming weeks. You can check it out here. (The last song in the player)
