Have you tried https://www.funkwhale.audio/?

It can be used effectively as a "private spotify". Labeling is a solved problem thanks to https://picard.musicbrainz.org/, and the fact that a lot of the music you buy these days comes pre-labeled already.

You then have a web-app (and/or a mobile app, if that's your thing) where you can stream music as you would with Spotify.

You can even build yourself a little music-sharing commune with friends, where you all upload the albums you buy and accumulate a nice collection of diverse tunes.

You still need to buy, upload and – the horror! – choose what you want to listen to each time, but perhaps it fills your other convenience needs.
