well i dont think its actually a song, i got DVD and when i put on english subtitles it always say what song its playing at the scene, when its a real song, but it this case its just nothing, i mean maybe that "song" its just sound efects from director.T.V.
Officialy its said that there are just these two songs used in the episode.
On The Radio - Wolf Like Me
Elvis Presley - Viva Las Vegas
The song is from a band called Agent Blue, who were a band from Stoke-on-Trent, Staffs. It's called Sex Drugs and Rocks Through Your Window. It bugged me straight away because I recognised it straight away and couldn't place it!
