What's it called?!

[McE]

What is the orchestral type piece of music always used on programmes like x-factor, on movie trailers and now being used on the e4 advert for reaper?!

[kempie]

I have seen an ad for Reaper that uses "O Fortuna", the opening section of Carl Orff's "Carmina Burana".

I think the piece of music you're after is "Requiem for a Dream" performed by The Kronos Quartet. Used on Lord of the Rings trailers, Britain's got Talent etc.
