What's the worst song ever written?
<|assistant|>
The 'Saturday Night Live' musical sketch "The Landlord Song", performed by Dan Aykroyd and James Coburn in 1976, has been widely considered as the worst song ever written. 
The song is described as "vastly unappealing" with the lyrics being "utterly abysmal".
