Artificial intelligence (AI) has proved a controversial matter in the music industry – resulting in legal tussles, job losses and a decline in musical quality. However, British pop icons the Pet Shop Boys argue that the technology can be used in a positive way in the creative process. The group's singer, Neil Tennant, said AI could'fill in the blanks' if a song has been left unfinished, such as when the composer is suffering from writer's block. Tennant and his bandmate Chris Lowe said they are looking at new technology as they prepare their'Dreamworld' greatest hits tour in Europe this summer. 'There's a song that we wrote a chorus for in 2003 and we never finished because I couldn't think of anything for the verses,' Tennant told the Radio Times.
