German has a word for everything, like ohrwurm. Translated literally as "earworm" in English, it's the word for songs that get stuck in your head and won't go away. What earworm of a song do you most dread burrowing into your head?
I can't think of an earworm that I hate offhand and most songs/tracks that I hate are easily replaced as earworms by listening to something that I love a few times on iTunes or the iPhone/Pod. My current earworm is one that I am actively cultivating by singing it over and over again in my mind; Eric Idle's "Always look on the bright side of life", which was chosen by my step-dad to be played at his funeral on Tuesday. I have always liked Monty Python and this track is perfect to remember my step-dad by.
