There’s another venue where “It’s a Small World (After All)” is on continuous loop: the mind of anyone who hears it. The song is a common “earworm,” a piece of music that can easily get lodged in the auditory cortex, the part of the brain that retains audio information, identified by researchers at Dartmouth College in 2005.
