I get earworms. It's not a medical condition, although it may perhaps be a neurological one. I'll get a tune in my head and it will play and play, and repeat and play some more. I think of it as K-REN, the soundtrack of my life. Today, for instance, I've got an entire set, including so far:
"I Feel Free" https://www.youtube.com/watch?v=Qb_Uu0eTNWk
"Denn alles Fleisch, es ist wie Gras" https://www.youtube.com/watch?v=yg7sU5B_ibM
I know, I know--it's a very weird playlist. I don't really have a good interpretation of why these pieces of music are insisting that I listen to them. These particular clips have ads, but you can usually skip them after a few seconds.
