On the Sky Sports News channel on Freeview, they play music (when talking about what's coming up next etc.). I'm sure it's from a movie but can't think which one. Anyone know?
The piece of music you speak of is Lux Aeterna, originally by Beethoven. It has been used in the film Requiem For A Dream, it has also been used in advertising campaigns such as Ryder Cup 2007 and the Six Nations. Hope this was of help.
