@snowdusk_ That Atomic Playboy song is from a famous demo, "Second Reality" by Future Crew. It was first released in 1993 at the assembly demo party. The song itself is by Purple Motion and is usually credited as "Second Reality II".
The song starts at 1:48 in this youtube video version of the demo:
