I buy mostly from bandcamp and Amazon.

I use Plex to host my music. It’s not super difficult to set up. And Plexamp is a pretty good player.

Plex also has the option for you to subscribe to Tidal, which I do. And the ability to stream my own music that’s not available anywhere on any stream plus almost everything out there that Spotify has is the best combo.

Jellyfin is another server like Plex, but I haven’t ever set it up so I don’t know how involved it is.

It was a few days ago. But it looks like it’s stuck now when I try to create new ones. Probably too much traffic at the moment.
