Got a tune that just won't get out of your head - known as an "earworm" in professional circles? It's because your short-term memory has been short-circuited. Coming down with Alzheimer's might be one way to cure yourself of the affliction, but there's a much easier path: chew gum. No, this isn't a surreptitious ad for Wrigley.
People actually study this stuff.
A 2016 study found pop songs and some classic rock standards often are big culprits. British researchers found instances of Involuntary Musical Imagery — aka earworms — are produced from songs with easy-to-remember melodies, fast tempos and repetition among other characteristics. The study found three of the most common earworm-inducing songs were by Lady Gaga, but Katy Perry, Queen, KylIe Minogue and yes, Journey, also made the list.
I think that's "Lady Gaga" in the photo, but who knows? I'm not a fan/follower of any of the insipid stuff that passes for entertainment these days. I did like Queen, just because they were so outrageously good when Freddie was alive, and because the surviving guys actually have talent. I think they were the first to consent to letting Weird Al do a parody of one of their hits, so they have a sense of humor as well.
Oh, anyway, back to the gum-chewing: the musical memories - earworms - are related to hijacking short-term memory, and oddly enough, chewing gum employs the same parts of the brain that are involved in short-term memory. Since earworms are involuntary activations of short-term memory, one effective way to block them is by overriding those parts of the brain; hence, gum-chew. Which I always thought was a term for "detective", but it turns out that that's "gum-shoe".
I never get anything right; there was a song many years ago, I think by The Association, which I thought involved Cherries. That, as it happened, was wrong - it was called "Cherish" - which for me changed the whole meaning of the song.
