Wham! Earworm

I woke singing a song from a karaoke dream. 'Everything She Wants' from Wham! was looping around my brain. You see, I secretly desire to have a mahvelous singing voice. It is one of the things that sealed my attraction to my husband. He has a deep raspy speaking voice, but when he uses it to sing...O, la, la, wet panties. Give me a bit of Joe Cocker any day.

So why do we get songs stuck in our heads? According to howstuffworks:

"Why do songs get inextricably stuck in our heads? Experts say the culprits are earworms (or "ohrwurms," as they're called in Germany). No, they're not parasites that crawl into your ear and lay musical eggs in your brain, but they are parasitic in the sense that they get lodged in your head and cause a sort of "cognitive itch" or "brain itch" -- a need for the brain to fill in the gaps in a song's rhythm.

When we listen to a song, it triggers a part of the brain called the auditory cortex. Researchers at Dartmouth University found that when they played part of a familiar song to research subjects, the participants' auditory cortex automatically filled in the rest -- in other words, their brains kept "singing" long after the song had ended [source: Prokhorov]. The only way to "scratch" brain itch is to repeat the song over and over in your mind. Unfortunately, like with mosquito bites, the more you scratch the more you itch, and so on until you're stuck in an unending song cycle.

There are many other theories about why songs get stuck in our heads. Some researchers say stuck songs are like thoughts we're trying to suppress...(bolding mine)

Somebody tell me ♪ why I work ♪ so hard ♪ for you? It's easy, just surrender, submit, can't say no. This works extremely well with a spouse who has OCPD.
