This thread had me in stitches!
I can certainly see the appeal of LMS, and d6jg does a fine job of "selling" it in many threads.
So much so that I'm tempted to give it a whirl, although I need to find somewhere to install it as I don't think my nas runs docker.
On the other hand, I installed free minimserver on my nas, and aside from the minor issue with having to restart it on a schedule so it refreshes its metadata (i.e. finds changes to my files / tags), using this with bubbleupnp on android to cast to the wiim is easy and has pretty much all the functionality I need. Easy search, random tracks / albums, (random) play artist, good queue management.
I sometimes miss the ability to see lyrics when streaming my own files - wonder if the LMS lyrics source is better than the often woefully incorrect lyrics I see on streaming services?
