Has anyone ever had a song haunt them? I've had this happen a number of times. The clearest and most persistent example I can think of is from before thanksgiving (US-November 23rdish) when Lush Life seemed to be following me around. In the space of five or six days, I heard at least five versions of that song in various places, including two instrumental versions, sammy davis jr's, and I believe peggy lee. It's happened to me with other songs, but that was the most recent occurence.
Of course nobody's version touches Ella's, but that's to be expected.
