Ever have a song stuck in your head? How about for 3 years?

Susan Root from England has suffered just that! She has heard "How Much Is That Doggie In The Window." She also hears "God Save The Queen", "Happy Birthday" and "Auld Lang Syne."

Mrs. Root suffers from what is known as "musical hallucination." It's not exactly the same as merely having a song stuck in your head. Mrs. Root actually hears the song in her ears as though it were playing through invisible earbuds. Sometimes it's so loud, it actually drowns out her husband. "How Much is That Doggie In the Window" is the tune Root mostly hears, but sometimes she also gets "God Save the Queen" and "Happy Birthday"



Have you ever had a song stuck in your head? What's your "earworm"?
