Quite faint in the background of that Guardian video is the music from Holst's The Planets Suite. Skipping lightly over the fact that it was playing Jupiter, there are two ironies in the choice of music: firstly, Pluto isn't a planet of course, and secondly, Pluto hadn't yet been discovered when Holst completed the suite in 1916.
Given that Pluto is the god of the underworld, perhaps a better choice would have been Offenbach's Orpheus in the Underworld. (If classical music isn't your thing, or you can't spare 10 minutes to listen to all of this, do at least treat yourselves by listening from 6m58s...)
