In general, Kubrick enjoyed listening to music – his wife Christiane had, in fact, mentioned in an interview that:
“He was addicted to music, he played it always, all day long. He worked with music, … classical and the pop songs and he liked jazz music. You name it, a very catholic taste in music.”
He’d listen to a wide range of music, at times, and select those pieces that excited him and felt appropriate for the scene – according to ever-so-reliable Wikipedia, it seems that in his last six films, he used music from existing sources, rather than commissioning a soundtrack to be composed – and the majority of this music was classical music. He justified this decision in an interview with Michael Ciment, saying:
“However good our best film composers may be, they are not a Beethoven, a Mozart or a Brahms. Why use music which is less good when there is such a multitude of great orchestral music available from the past and from our own time? When you are editing a film, it’s very helpful to be able to try out different pieces of music to see how they work with the scene…Well, with a little more care and thought, these temporary tracks can become the final score.”
