audio player (Media Utilities must be installed) - Play/pause icon actually changes!
If you have trouble, please email me.
Made on Nexus 4 with Nova Launcher 7x5, no margins and dock as overlay.

Pimp your phone!

If you can't get the audio widget to show info, be sure you have Zooper "allowed" inside Media Utilities app.
If the play and pause icons doesn't change, open main Zooper app, select widget, and go to the advanced parameters at the play icon, and edit the path of the sdcard to match the folder with the pause button. (Sdcard/ZooperWidget/Bitmaps/musicpause)
