Mostly not-unpleasant sounding, but only "musical" in a couple of spots. "Seashore" and "birds chirping" were rather strange to hear that way, "gunshot" would have been a lot more annoying if it had been a lower number, and one of the drums sounded more like a trash-can lid on the high notes. Mostly it just sounded silly.
I played the same file on another machine (and a different OS), and got the same mapping, ruling out the "this player is broken" diagnosis -- which leaves, a) the list I copied from is wrong, b) the standard is implemented commonly in two different ways as you described, or c) the version of abc2midi I'm using is wrong. Honestly, now that it's been mentioned (thanks, by the way), 'b' isn't all that surprising. MIDI had to grow up kind of fast.
