Why is call hold music always so distorted?

Do they use crappy quality music or is it something about it being sent through multiple things to get to the user on the call, that makes it shitty quality in the end?

The telephone system is designed for carrying human voices. It has very limited bandwidth, so we actually add compression onto it as well. This is why someone doesn’t sound the same on the phone as they do in person.

The compression that we do for human voices makes music sound even worse. This is because music has a much bigger range of possible sounds than the human voice, so the compression takes it even further away from its original sound.
