Chances are, you've fallen victim to earworms — pesky songs or melodies that get stuck in your head and just won't get out.
Research suggests that there are psychological reasons why some songs are more likely to stick, including memory triggers, emotional states, and even stress. Some researchers hope to better understand why this happens and figure out what, if anything, music memory can teach psychologists about how to treat patients dealing with memory loss.
NPR's John Donvan speaks with psychologist Vicky Williamson about the reasons some songs get stuck in our heads, and the implications it has for understanding human memory.
