Read Me The Riot Act
I’ve got Elvis Costello stuck in my head, which is curious, because I haven’t listened to this particular song in a while. At least, I don’t think so. After your playlist grows beyond a certain size, it begins to contain its own internal neighbourhoods, its own nooks and crannies. Who knows what lurks in the dark depths, etc. It’s trivial enough to check, but one must allow some small mysteries to persist in one’s life.
Also, it’s strange that a song stuck in your head can actually override what you’re listening to: in this case, Interpol and Kenickie. I can recognize ‘em, but they’re not registering at all through the internal din of the One True Elvis. The all-curing Internets do have a machine for cancelling out earworms, but I fear that the cure may be worse than the disease. (After all, I do like Elvis Costello.)
