I think it would be awesome it spotify had a visualizer that synced up with the music. It is a feature I use in iTunes when I have company over and I believe Spotify would benefit from having one.

Thanks to everyone for their contribution to this thread. We really appreciate it. In the interest of full disclosure, we’d like to share with you the status of this request.
After serious consideration, we’ve decided not to introduce a visualizer for the desktop app. As a result, we’ve marked this idea as Case Closed.
While we know this is a popular request, we don’t feel the majority of listeners would benefit from the addition of a visualizer at this time.
Thanks for understanding, and please keep those ideas and requests coming! Together we can make Spotify the best it can be.
