Ear worms

If your life's personal soundtrack is made up of your ear worms, I'm not sure I want to know what my plot is.  For the past, oh, six months, I've had recurring:

• "O Tannenbaum"/"Maryland, My Maryland" (same tune)
• "Strangers in the Night" (I don't even know the lyrics!)
• "Enterprising Young Men" (from the new Star Trek)
• James Bond (theme)
• Gerswhin's "Piano Concerto in F" and "An American in Paris"
• "Singin' in the Rain"
• "Good Mornin'" (from Singin' in the Rain)

"O Tannenbaum" has been the worst offender.
