I've avoided using it because of concerns about library size. I want to move off of iTunes (launch a VM just for this) but nothing else seems to really handle managing a library. Currently trying out Airsonic but it is kind of slow and I can't edit tags with it.

Maybe time to give Plex a try for this.

I use LMS (Lightweight Music Server), which is xSonic compatible: https://github.com/epoupon/lms

I run all songs / albums through MusicBrainz Picard before putting them in the music directory structure so they're fully tagged. It only misses some of the more local / esoteric stuff I've got.
