Mr Mitchell is the founder and boss of a website and app called Boomy, which helps its users create their own songs using artificial intelligence (AI) software that does most of the heavy lifting. You choose from a number of genres, click on “create song”, and the AI will compose one for you in less than 30 seconds. You can do things such as add or strip-out instruments, change the tempo, adjust the volumes, add echoes, make everything sound brighter or softer, and lay down some vocals.
