Very interesting research! Music has a unique effect on us. I wonder if poems (or other related art expressions, like script lines from a movie), can have this earworm effect. And if they do, can they be as intense as a song?
I love exploring and writing about music effects and one of the things that caught my attention is a somewhat opposite effect of earworms: songs that appear over and over again without causing that effect but don't become obsolete either.
Maybe you'd like to read it and give me your opinion on this:
Anyway. Thanks for sharing about this fascinating effect! Oh, and I think I'll pass on listening to your examples, for fear of having an earworm I won't be able to get rid of ;)
Cheers!
