The phenomenon where one hears a song, then can't get it out of one's head. Transmission occurs when one person sings or mentions the song, and the second person then begins suffering the same symptoms.
Colby heard "Get Up, Stand Up" on his car radio on the way to the gym. He hummed it intermittently during his workout and sang it in the shower. Later that evening, seventeen people had "Get Up, Stand Up" going through their heads without knowing why -- they had contracted the song virus.
