The orchestral theme by John Barry was featured throughout the James Bond movie, 'You Only Live Twice'.
You can also see the music in opening and closing credits of the movie.
Robbie Williams also uses this as a background music for his Millennium song back in 1998. As the Wikipedia entry notes:
The song borrows heavily from the musical arrangement of John Barry's "You Only Live Twice", the title track of the 1967 James Bond film of the same name, said to be one of Williams' favourite James Bond movies. However, it is a re-recording in a slightly different key instead of a direct sample for reasons of cost.
