You know about Apple Music and Spotify. Prizm is a little different. It’s a futuristic- looking speaker that sits on your desk and cleverly plays music it thinks you’ll like. You simply have to train it by creating a pro le and liking or disliking music that’s played. Prizm goes through its catalog of music through Wi- Fi, analyzes the time of day and the environment, then plays the tracks it thinks best suit the moment.
