Audio Visualizer?

[graysonk95]

I tried unsuccessfully to post this in the Android OS forum section, so I'll try again here in the more lively S4 section.

My friend at work has a cheapie smartphone running vanilla Android and whenever he has music playing his lock screen background, rather than displaying the cover art, displays an audio visualizer.
Having an S4 w/ 4.4.2 I have looked everywhere to try and replicate this behavior.
He uses Play Music and Pattern lock, and I have looked through all of the settings in both and can't find anything about a visualizer.
I turned to third party apps but they have a major limitation- they are live wallpapers and if you make the lock screen live on our phones the home screen mirrors it, which I don't want. Also the lock screen doesn't allow unlock effects with a live wallpaper.
It seems his visualizer is a function of the "music is playing" lock screen.
Where our default lock screen shows the cover art when music is playing, his shows a visualizer which I think looks a lot nicer.

Any help?
I'm guessing this be a feature Samsung tossed out?
