Another way to look at the whole sound thing is; even if the sound was true Stereo (which MP3s are not), and some great sample rate like 96khz 24bit, the music and effects would still have to be compressed in dynamic range so that the sounds would stand out in a noisy location (like a bar or arcade).
Pinball music is compressed or "stepped on" to make the quiet passages louder. Otherwise you might not hear any of the subtle parts at all. Then the songs and sounds are EQed to maximize the sound coming from $2 speakers.
Back in the day, 45s were compressed kind of the same way so they would stand out when played on a jukebox. Otherwise softer passages would be perceived as "dead air" in a noisy bar. The louder your song was, the more it might stand out and be noticed by bar patrons. The song "Whip It" by DEVO was so short in length and thus could be cut so "hot" on vinyl that it was often the loudest song in the jukebox by far - fans loved it. The 45 is much louder and more distorted than the 33 album cut of the same song.
