I created simple Mopidy HTTP player that is hosted online.
The advantage of this solution is that you get all updates as they appear, just by reloading the page. No need for local installation and managing updates and you can try it just by visiting the page.
It’s still possible to use it locally howerver.
I tested it with Mopidy 1.0, local files backend and mopidy-gmusic plugin, but I hope it will work fine with spotify and others as well.
It’s written in Ember.js and is styled using basic Twitter Bootstrap.
I hope that someone will find it useful.
Edit: I don’t know why discuss tries to open HTTPS version of above link (it must be HTTP because of web socket connection)
