I heard quite recently that having a song stuck in your head, is just a minor indication of insanity.
Anyone like to elaborate on this?
Since the “earworm” phenomenon is extremely common, I doubt that it has anything to do with insanity. Neurosis, maybe.
This may be of interest to you.
If you find a citation from a reputable source for the insanity connection, I’d love to see it.
Nonsense. (I am a licensed psychologist.)
Oh, fiddle. Every time I see the username Shoshana, I start hearing “My Sharona” in my head. 
Not on this board, but elsewhere where my user name is also “Shoshana,” I have seen it turned into “Sharona.” Nobody ever has this trouble with Susan!
“MO”
“MOR”
“MORNING WOOD”
…
“to the nth degreeeeeeee”
Carry on.
And I start hearing “Shoshana” in The Name Game Song. Shoshana, Shana, bo Shana . . .
Its almost a fact that the songs that are stuck are never the ones you really enjoy, either.
hears the faint sounds of What Is Love heading toward my brain…
Welcome to the boards. 
Around here, we like to stamp out ignorance.
It usually helps if you could tell us who told you something, so we can judge their authority for saying it.
For example, I heard quite recently that:
- perpetual energy has been invented (from a company who want money from investors)
- a ship teleported from Philadelphia (from a guy who wrote a book he wants people to buy)
My purely personal opinion (note that a psychologist has already posted) is that it’s not true. When playing chess, I sometimes get a tune stuck in my head for the duration of the game. It doesn’t affect my results.
To be That Person: I had two running through my head yesterday – Walking With the Ghost by Tegan and Sarah and *Kamikaze *by PJ Harvey – that I quite enjoy, personally. It was only annoying when they started blending together.
It isn’t just melodies that get stuck in the brain. Mark Twain had the problem with a bit of doggerel:
(you have to scroll down)
I haven’t heard of the second, but I do enjoy the first one. The one stuck in my head was a bit inaporopriate for church services though. We Are Scientists- Nobody Move Nobody Gets Hurt
Have you guys seen the movie, “Touching the Void”? It’s a documentary (with re-enactments) about these two mountain climbers and the hellacious experience they have (well, one of them in particular).
Anyway, at one point, one of the climbers is seriously, massively, injured and dehydrated and pretty much at death’s door, and he gets a song stuck in his head (“Brown Girl in the Ring” by Boney M) and it almost drives him crazy. (At this point in his experience, he’s also hallucinating.) In his interview, IIRC, he says he didn’t want to die with this song in his head, as he didn’t even like the song.
Considering he was suffering from dehydration- and trauma-induced psychosis at this point, this would support the OP.
Ah, I’ll keep that in mind when posting such things.
Thank you~
Nope. It just supports the idea that psychosis doesn’t protect you from having a “song on the brain.” The other examples in the thread, plus the evidence cited, plus my earlier professional statement as a psychologist, suggest that the phenomenon is widespread, exhibited by people who are not insane, and not a marker of insanity.
