Working good here on my Moto G. I do notice the animations stuttering a little bit, but apart from that, its all fine. I can define this player as beautiful yet lightweight (consumes about only 20MB RAM average, same as Apollo). Also, in my opinion, thats the best material design music player out there (CM12's new player, aka "Eleven", works only on Android 5.0 and up, ACEMusic is still in beta and crashes a lot, and Shuttle consumes too much RAM), so you made some pretty good work here, mate. Keep it up! Oh, if I had a credit card... I would buy that Pro version.
