Why is hold music the worst?

I've been sitting on hold for over FOURTY minutes... hearing the same loop of terrible airline hold music...and I want to die. I have no sanity left. My phone is on my desk with the volume turned down as low as I dare...but still it's driving me nuts. Why is hold music the literal worst? Is it just because you're annoying that you're waiting to being with, so no matter what it'll be annoying?? Send moods.
