That's kind of where I am as well. I initially ripped my CD collection to flac in around 1999 or 2000ish. Since then I've only added CDs I've bought or flacs I've purchased to this "main" archive (I have side areas where things got acquired through less than legal ways). My main archive is roughly 500 GB. Since I use Apple stuff, I have a script that will transcode it to AAC and copy it to my laptop where I have keep this (annoying) duplicate copy (80GB). Apple Music then syncs that stuff to its cloud. I used to use Subsonic on my phone to listen to my music directly, but Apple Music is so nice since it seamlessly merges my main library with its streaming stuff. Nowadays I seem to use Apple Music for like 90% of my "discovery". And I still slowly buy up songs that end up making the cut. I'd like to transcode to Apple Lossless and have _that_ in the Apple Music cloud instead of AACs but I don't want 500 GB of music on my laptop. Somehow I can forgive 80 GB, but 6x that crosses my line… Perhaps I could use a mounted network share as my iTunes library, but I suspect iTunes won't be happy when part of the backing store constantly goes away and comes back later.
