you're right, a midi is the blueprint for the song, it's your sound card's job to realize it, if you dont have proper soundfonts or proper midi hardware (preferrably midi hardware) you won't hear the full range of the song.
Unfortunately I don't have the appropriate soundfont to do it as it "should" sound (the old soundblaster midi, if anyone has a old SB Live or Audigy 1/2 install disk I would appreciate if you could PM me, my disk is long gone but I could really use the .sf2 file from that disk) so I rendered it with the soundfonts that I do have, only two really stood out, all the others basicly sounded the same and my casio ones didn't have all the proper notes so half the song was missing (I guess stones used some instrument channels that not all patchsets/soundfonts have), but there they are for anyone who never heard the old versions of the songs and don't have the midi support to even try.

@Zosimus There was no offense, I just thought it silly to post a link that went to a page with nothing but another link to click, just save everyone the time of the extra clickthroughs and pageloads.
