Interesting side note: demos tend to use music with pentatonic (ambient) or whole-tone (dreamy) scales. They’re easy to harmonise, which makes it easy to procedurally generate decent-sounding music.
When watching demoscenes these days I find myself always waiting for the dubstep 'drop'. Sadly I think modern music is starting to spoil this sort of thing for me.
