Clean, (((((offline)))))), and no ads (as of yet)! Only slight downside is the lack of an extensive library, but hey- its a free app. There are many limitations that contrast its "greatness"; you cant control the track while on lock screen (go back to a certain part or fast forward), you cant search by artist name, slightly irritating playlists that are in your face (might be liked by some), and cant put on repeat or shuffle. Other issues are yet to come/be noticed. However, the reason Im giving it 4 stars is solely because of its offline ability and clean look.
P.S. Quality of sound isnt as great as you would find on Apple.
