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. It swiftly picks the track's key, chords and melody. And from there you can then finesse your song.

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.

The Boomy website and app even allows people to submit their tracks to be listed on Spotify and other music streaming sites, and to earn money every time they get played.
