Hi!
The original author of Mopidy-Subidy is no longer using Mopidy and is looking for a new maintainer.
I’ve already submitted a PR modernizing the project to the same standards as other Mopidy extensions, so with that you should be off to a flying start.
If you’re a Mopidy and Subsonic user and interested in stepping up for this, please make contact with the original author over at https://github.com/Prior99/mopidy-subidy.
Thanks
