What's the worst song ever written?
<|assistant|>
It's difficult to definitively name the 'worst song ever written', as music is very subjective and personal. But some songs that come to mind that get a lot of negative attention include 'Happy Birthday' by Madonna, 'We Built This City' by Jefferson Starship, and 'Gangnam Style' by PSY.
