Amazon Music Helper — suabo

Amazon Music Helper is a browser extension which helps you add tracks to your favorite playlist and send notifications with next song information. The extension will add an icon to your browser bar. This way you can add the currently playing track without the need to switch into the browser window/tab with Amazon Music playing. The extension will grab your existing connection to amazon music and use it to make it happen. This way you only need to listen to your music like you would normally. If you use the shortcuts you can even hide the icon in the toolbar by customizing your toolbar.

This Add-on is Open-Source and the source code is free to view on github (https://github.com/suabo/amazon-music-helper).
