I would love to help with material design. I could prepare new concept and unique style. I have many ideas for this and it could be "just a reskin" or completely new concept. Contact me if you would like to have some help with that   https://plus.google.com/+ArturOleszczuk1991/posts/ccEuRMuWY7n It's not my whole idea, I made animations concept for other music player, but just to show what I'm capable of.
