Spotify joins many other companies using artificial intelligence for its service. The app beta tests its new DJ feature in Canada and the US for Premium users. With an AI-generated voice, the app can create a customized radio station built around your musical taste. It isn't too far off what it's doing now with algorithmically-generated playlists. But now, you'll hear a voice intro and commentary we've typically only gotten from the radio experience. If you aren't feeling the recommendations it offers, there's the DJ button you can switch to change up the tracks.
