Babalon A.D. (So Glad for the Madness) is a DVD single by Cradle of Filth, released on 3 March 2003 by record label Sony.

The video is an homage to Pier Paolo Pasolini's famous final film Salò, or the 120 Days of Sodom, based on the Marquis de Sade's novel.

The video on the camcorder shows the Cradle of Filth band members in something like an empty dance hall, sharply dressed, systematically abusing and humiliating half a dozen young men and women, while Dani directs proceedings with a megaphone.

Near the video's end, Dani is seen looking at himself in an antique mirror, which he then spins around and points at the camera operator, revealing that the maid herself was recording the band's activities.

Back in the bathroom, the footage on the digital camcorder cuts off and the maid looks up with terror etched on her face.
