The wonderful world of emojis just got a bit more exciting, as Skype announced that ex-Beatle Paul McCartney has dreamed up the inaugural batch of audio “mojis” for the popular messenger service.

And at the same time it was musical so it was great practice for me in the studio.” As far as we can tell, mojis are just like regular emojis, except with sound. All we can say is ? ? ? ?
