Works! Update (12/5/2015) Doesn't work anymore
It worked great for me, and it actually fetches the correct song, unlike the old lyrics app I was using with Google Play Music. Love the autoscroll. Maybe the icon on the bottom could be sharpened up... looks a little blurry at full screen. Excellent! Update (11/25/14) Doesn't work anymore. Window comes up blank.
