Like most people I do have occasions when songs get stuck in my head. However, I also have the problem of songs appearing in my head whilst I’m asleep, so that when I wake up — and it doesn’t matter what time, even the middle of the night — it’s there, playing away merrily. Last night I went to sleep with White Stripes’ Seven Nation Army. I can live with that despite it being second-rate Pixies with only one guitar to share between them. I woke in the middle of the night, sometime just before dawn, I guess. Horrors! I was confronted by Britney Spears’ Me Against The Music. What a hideous event! To be invaded by a song that sounds like a chorus of moaning teenagers. Ugh. Thankfully, I pressed the Red eject button and Ms. Spears was removed from the building.
