iTunes's series 6 soundtrack has two tracks for this: Tick Tock Round the Clock (seems to be sans vocals from the preview - which I believe is taken from Night Terrors) and Tick Tock (Vocal Track) (which appears to be a compilation of all the Tick Tock vocals).

Tick Tock Round the Clock appears to be the official name of the piece...
