On Hold

I realize that when on hold, a phone system has to have music or some sort of noise so you know you are still holding and haven't been disconnecting. I am pleading with you, phone system makers, please don't make this the most annoying, repetitive, hold music on earth. I still need to be able to think when I finally get to talk to an actual person. And when that actual person puts me back on hold to figure something out, maybe you could switch the song up a little. How does the song never end? Don't all songs end?
