2001 et al
They had the music from 2001: A Space Odyssey onboard.
They also apparently had the music from the 1969 film Marooned as well!
In a related vein, here is a list of the wake-up calls for most of the manned
US space missions. For some reason, Apollo 13's are not listed (if they even
had any before the accident and I presume they had none after the explosion),
but Apollo 15 and 17 had the 2001 theme music played to them.
