This electronic pop tune was originally penned by Scottish synth pop songwriter Calvin Harris for ex-Moloko singer Róisín Murphy. She rejected it and an offended Harris called her an idiot in print. They subsequently made up and Murphy now has a songwriting credit on the song. "Róisín was right. The original version was s--te," Harris admitted later to The Independent on Sunday.
New Order took the title for "Blue Monday" from an illustration, which read "Goodbye Blue Monday," in the Kurt Vonnegut book Breakfast Of Champions. The image referred to the invention of the washing machine improving housewives' lives.
