Since the Amiga had the most powerful audio capabilities at the time, Hülsbeck most likely composed the song with this platform in mind.
The superior 8364 audio chip gives the song the highest fidelity sound of any of the ports.
The Atari ST port outputs the music on a YM2149.
The Commodore 64 port outputs the music to the 6581.
For the DOS port, Matthias Steinwachs converted the song into Ad-Lib's ROL format. Unfortunately, his conversion process lost a lot of the instrumentation near the middle of the song. It's played on an OPL2 chip.
