I was explaining to someone the other day that I always have some tune “playing” in the back of my mind. I’m functioning normally otherwise and can think reasonably clearly. I suspect that this is probably due to some mixture of the fact that I play music by ear, and that I have lousy concentration in general. (The latter may be the EFFECT, not the CAUSE, though.) The song du jour is often just the last song I heard on the radio on the way to work, but it’s sometimes one that was apparently suggested by a conversation or event. Typically I can figure out why it’s that particular song at that time.
At any rate, the person thinks I’m loony, and of course he may be right. My question is whether this phenomenon is widespread, or if I’m some sort of middle-aged ADD victim? As you read this, and assuming that there’s no music playing where you are, is there something in the “Now Playing Mentally” display?
