I'm okay with appliance making cute little dings or buzzes but if they chime out a full song it creeps me right out. I'm gonna get the clothes out of the wash you don't have to scream "Mary had a Little Lamb" at me.
Fun fact: back in the 90s, some motherboards would start playing "Fur Elise" or "It's a Small, Small World" through the internal speaker if the CPU fan was failing. So if you started hearing that, that meant your computer was about to fry itself.
