Well, one notable absence on the list above is the Atari ST version, it, Amiga and DOS being the first 3 ports of Lemmings released. And remember, Lemmings have been ported to just about every system on the planet. Just off top of my head, here're a bunch of systems not mentioned in the list:
- Commodore 64
- Phillips CD-I
- there's a CD-ROM version of Lemmings for DOS that actually has the music as audio tracks in the CD (and I don't mean mere recordings of the adlib/TGA music, but music specially made for the CD version).
- Windows (you've heard this if you heard the MIDI versions of Lemmings music from the XXXLemmus styles for Cheapo)
- Macintosh
- Nintendo (as in the old 8-bit NES/Famicom, not Super Nintendo)
- Acorn Archimedes
Granted, I haven't heard the music on many of these systems listed above, so some of them might be very similar to the ones listed in the poll.
