The PC speaker could only play square waves, and had only one voice.
There is no "correct" sound for a MIDI file as it's just note and tempo data. But many people probably associate them with the OPL2 synthesizer chip on AdLib and early SoundBlaster cards. [1]
Now that we have high fidelity digital sound output on even the cheapest computers/devices, at least 44 kHz, at least two channels, and at least 16 bits per sample, we can emulate (or play a recording of) anything.
[1] Personally I remember this midi file sounding different/better. Maybe because I'm remembering using a Sound Blaster AWE64 while playing these things in Windows?
