Did you know 98% of people experience "involuntary musical imagery"? It irritates women more than men (yeah, I can second that research).
In Germany, an earworm is known as "ohrwurm", a type of song that typically has a high, upbeat melody and repetitive lyrics that verge between catchy and annoying (citation).
I actually avoided posting videos of some of the more hideous of the earworm-age like any form of Christmas music (I HATE "Jingle Bells", especially when my students sing it...in May) or Disney's heinous "It's a Small World" (that ride is nicknamed "The Asylum" amongst employees, which I can well imagine).
Earworms are part of the reason I can't listen to music when I'm writing a first draft. I'm way too easily influenced.
What's an earworm that drives you bonkers (if you can think past all the earworms I just threw at you)?
