Currently it looks like HA uses the python-mpd2 library in the mpd integration. This library does not (as far as I can tell) have support for pulling in album art which I would like to have in the UI. So I guess we could update that library OR convert to one that has support to pull in the album art - one such library is here.
I don’t assume anyone would be averse to pulling in album art but what is the preferred method? Update current library or use a new one?
I’m willing to do some work on this though I haven’t contributed yet and would stumble my way through a bit … sounds like the best way to get started
