I think I played it on PC back then, but I am not 100% certain anymore; could have been on Amiga too. Interestingly the Macintosh version looks the best to me therein, but I am also not absolutely sure about that since it seems to be differently scaled than the PC version. I wish I would have noted down back then what I used and played. And when.
Have a listen of the intro song. They are quite distinct on the different soundcards and machines. This might trigger your memory to identify which music is the one you heard all those years ago.

The music for the second part is even more distinct.
