That was my move as well. I already had a decently sized NAS with Plex that was accessible anywhere. The music experience through GPM and Spotify is better, but at least I can manage the music myself and I never have to worry about it going away (or some weird licensing or exclusivity issue not allowing me to listen to something I want to listen to). And my bootlegs, b-sides, remixes, and rare tracks that you can't get on streaming services is preserved too.
