I started working on a headphones module and have it working pretty well 100%. Its not looking the prettiest at the moment but it works... For those game enough to try it out its on my repo at
https://github.com/N3MIS15/maraschino/tree/headphones
A couple things are holding me back from sending a pull request to master. The first is the styling is not finished (not a big deal..) The second is a bit more serious, The Headphones API is very new and not yet complete. These are a couple things i have noticed..
If the wrong user/pass combination is sent headphones will ask for the correct user/pass before proccessing the request (it asks for user/pass in python terminal).
When doing things like adding artist or refreshing artist. maraschino will not be responsive until headphones has completed that task. This can take a long time for artists with alot of albums.
If you do decide to test it, please send any requests/queries to me in a pm.
