The related C64 cracking scene also begat the demo scene. The flashy crack intros with sprites, scrollers, and raster bars became the flashy demo intros, and from there they learned about a wonderful thing called "design".

Keygen music is another similar relic. They are chiptunes included in cracked software. Their names were often just whatever software they were cracking. I like Adobe Create Suite 4 here https://youtube.com/watch?v=FVX6t-ivMfE&feature=share

I sometimes just opened keygens after I was done cracking, just to listen to it more.
