Steven Wilson has shared a surprise Christmas single called ‘December Skies’ after being challenged by a friend.The Porcupine Tree frontman uploaded the track on December 14, where he shared the story of the unusually festive track.On YouTube, Wilson shared he was “challenged by a friend last week on why I’d never done a Christmas song.”“I protested it wasn’t really me, and besides I didn’t think I had it in me to write suitably Christmassy lyrics,” he continued. The friend suggested they use Chat GPT to write the song instead, where they instructed the AI to “generate Christmas lyrics in the style of Steven Wilson.”“I was shocked at how instantaneous and easy it was to guide it”, Wilson said.
