Then for some unexplainable reason, it got removed. Just type in the top left search bar spotify:app:visualizer and a Spotify visualizer app should appear for you. It would be cool to have a music visualizer that syncs with music that's built into Spotify. A Spotify visualizer was implemented in the desktop version of the app a while ago. The Spotify visualizer software starts by analyzing the waveform and frequency information in the audio, and it looks best as a screen saver. Music visualization, a feature found in electronic music visualizers and media player software, generates animated imagery based on a piece of music. A music visualizer works by extracting waveform and/or frequency information from the music and feeding this information through some display rules, which produces what you see on the screen.
