Usually, I have some inkling why a persistent earworm sprang to mind and stayed there. I might have heard the song on the radio, pulled it from my collection and played it, heard it in a store, or read a phrase that reminds me of the song's lyrics. Sometimes, however, I'm stumped.
In recent days, "Too Many Walls" by Cathy Dennis has stayed firmly in my mind. I remember KYKY playing it during its Summer '91 ascent up the charts. I haven't heard it on the radio in ages, though, nor have I seen any recent reference to it online. I also haven't felt claustrophobic lately. Why, then, has it been on my mind recently?
As my high school principal once said, "I am not all-knowing. I cannot answer every question in life I want to answer."
