Earworms: How do you dislodge one?

For some reason I am highly susceptible to earworms. "And baby pulls her hair for a Vicodin. She falls flat on the bed again, mutters something about the end while covering her eyes with both her hands." The title is Guts, from Swedish singer-songwriter Augustine, and I was stuck with this song for nearly six hours before it finally went away. Researchers still haven't figured out what causes earworms, but according to science there are five ways to get rid of them.
