Visualizations are plug-ins that display geometric shapes and color on the Now Playing tab when you play music. Visualizations are grouped together into collections. You can add and remove visualizations or download additional collections from the Web. You can also display special enhancement controls to change video settings, play speed, or audio levels with a graphics equalizer, choose color effects, and send a media link in an e-mail.
Select Visualizations

Click the arrow below the Now Playing tab, and then point to Visualizations.
