Ordinarily, when a radio air check CD I've made only plays in one speaker, I think, "Why was this in mono instead of stereo?" When it's from the early 2000s, however, I think, "Ah, (former family cat) Sammy must have chewed through a speaker cord."
Instead of being irked that the CD isn't playing in stereo, I think, "He was a good cat. His sister cat, Rosie, and he listened to a lot of good music and interesting radio shows with me."
Those are sensible priorities, I think.
