Quick CSS Fix / Pet Peeve for Widget Controls

For some reason you’ve inlined style="opacity:0;" inside a.previous, a.play, and a.next inside of class-sonaar-music-widget.php

And then you’ve had to use opacity: 1 !important; for all three of them inside sonaar-music-public.css.

Besides being unnecessary, when someone unloads your style sheet and wants to style their own player, they at first don’t see the player controls at all and then have to throw in the !important rule into their own styles. Just get rid of the inlined rule and then you can get rid of the !important rule as well.
