Old
The New one would get annoying after a while, and they cant change the theme that BBUK Is knowen for.
BB USA is known for its **** and boring soap opera theme.
BB UK is known for its upbeat dancey theme tune.
So use the original!
Plus they wont use the new one anyway, that was the extended advert.
If you look at the BB10 extended advert they had the new sounds that everyone thought would be in the titles, but sadly it wasnt.
Btw, good choice..you know picking BB9s titles
