Peacemaker is a free app that will suit anybody who wants to mix up some music for themselves. It is integrated with both Spotify and iTunes, making it quick and easy to download tracks and playlists. Then, once you have chosen the music you want to play with, the AI DJ will help you to mix the tunes into something new and exciting. Casual mixers will have hours of enjoyment playing around with tracks, while those with more professional ambitions will find it a useful starting point for trying out a few new ideas and perhaps hitting on some new inspiration.
