A different song is used each week depending on what the theme is that week.
It varies each week depending on the theme.
It was (in fact) Simon Cowell himself, who composed the X Factor theme tune!
I think The Script played the music to the theme, but I dont know if they wrote it. But I'm not even sure they played it. On their Wikipedia page, it says there music is featured in lots of T.V. Programmes including Waterloo Road, so, I'm not sure of the answer but I hope this information helps!! x
The theme tune "Deeper Love" on the Film4 advert is sung by the artist Allie X.

Musical Heroes.
X Ray Dog wrote it trying to find the name.

Tune X was created in 2011.
