Fortuna Imperatrix Mundi
) from Carl Orff's cantata Carmina Burana
was the first thing that popped into my brain when reading the title of this thread, but when it comes to cinema I remember being mightily impressed/petrified as an eight year old by Jerry Goldsmith's The Cloud
and V'ger Flyover
from Star Trek: The Motion Picture
. BTW, Zdeněk Liška's score for the 1963 Czech(oslovak) sci-fi film Ikarie XB 1
- in particular the cue heard during the film's climax as the titular starship approaches the "White Planet" and we see an alien megalopolis on the bridge viewscreen - is certainly not
appropriate listening for those who may be semi-seriously contemplating suicide.
