Speaking of film and music, I will add my five cents.
One of the best sci-fi films for me is Johnny Mnemonic, because it visualised my fascination with cyber-punk (William Gibson and others) as a genre.
This movie has an excellent soundtrack, and I would like to point out at least two songs here (yes, I know it's not according to the rules) but I can't help it :)

Cop Shoot Cop - 3 A.M. Incident
It's a story that perfectly fits the situation in the movie

and

Orbital - Sad But True
Electronic sounds, I can't say techno/house because is an old one, but I really enjoy in the scene where this music plays and Keanu Reeves came to the bar. I think that authors of the Fifth Element use this as an example for the Diva :)
