At the end of season four of Doctor Who, when Tennant's Doctor is towing the earth back to its proper place, the track playing is "Song of Freedom".
In this track, there are some chanting voices. Does anyone know what they are chanting, in what language? Do the lyrics have any hidden meaning? Or maybe they are only chanting noises, and not necessarily actual words.
P.S. I wasn't sure if this fit better on Movies & TV or Sci-fi & Fantasy. It's not specifically about the sci-fi plots or technology or species or anything of the show (as far as I can tell), so I opted to put it here. If an admin thinks it'd be better on SciFi&Fant, please move it.
