Very nice! Though it looks like your micro inverters are mounted right where water would be coming through, looks like they would be easy to relocate though. It is possible to use a combination of t-molding on the top along with caulk between the panels to reduce water penetration cheaply and easily, while not being 100% water tight it gets pretty close.
I use Emby and catalog my music using MusicBrainz Picard. Before Emby I used Ampache but I want to serve up as much of my media through the same interface as possible. Adding all the proper metadata and sorting the music can be time consuming, but it makes all the difference in serving up the music properly. Music is much more varied than Movies or even TV so it is a bit more difficult to get right and there are sooo many artists. MusicBrainz Picard makes it pretty easy though. I will be checking out Beets.io after reading this thread to see if it can help any more with organizing my library.
