The worst song ever written was the one I wrote a couple of months ago. What is really strange is that when I first wrote the song the melody was clever and original, the words were witty, wise etc. The following day I noticed a slight deterioration. Perhaps the melody was not quite as original as I thought, and the words not as witty. The day after that I looked at it again and found that it had got even worse. The tune was derivative and had been plagiarized from inferior sources: the words, when comprehensible, were tacky and embarrassing. That night I looked at it again. Impossibly it had deteriorated even further. My only cconsolation as I disposed of this pathetic little horror was that I had subjected no-one else to it.

But that was only marginally worse than one I had written a month previously. Also RIP

And that was only marginally worse than one I was commissioned to write and recorded for … Oh, enough!

When it comes to talking about the worst song ever written I would have a long.longway to go before I started talking about someone else's work.
