Presently, I don't have. However, have had some monster ear worms in the past. Probably the worst (in terms of how long it lasted; almost 2 years of "hearing" it in my mind near constantly) was an E. Power Biggs recording of Bach's Sinfonia to Cantata 29. I had learned to play it on organ for a wedding, and had used that particular recording as an audible aid to check myself against. I really like the piece of music, but man, I just couldn't escape it. It went on so long, that when the streak finally ended, I woke up in the middle of the night and almost thought I'd died, as I heard only silence.
Supertramp's Bloody Well Right is another one that remained "stuck" for a while.
