For the last two days, an old Billy Joel tune has been bouncing around my head -- "Streetlife Serenader." But here's the thing: I inadvertently replaced the words "streetlife serenader" with "midnight masquerader." I even sorta imagined the album featuring that title. Now, the phrase "midnight masquerader" is indeed in this song ... but in my head I replaced all the "streetlife serenaders" with it.
I've heard the song, literally, a few hundred times. How does something like this happen?
