What I don't understand is that the free music server software that I use, Logitech Media Server, has full Spotify family, Tidal and Qobuz integration, and it's basically all done by one guy part time. It works well - it now integrates your Qobuz favourites into your main library. I don't know if he has some magic 'in' with these companies, but he has created a good, working solution.
Meanwhile the music server software that I pay for, MediaCenter, does not have any meaningful online integration. It has a number of coders who work on it, but the system that will obviously become standard for music reproduction, streaming from your provider of choice, is not something that appears to be under development at all.
I know it's a bit of a hassle with competing providers (I guess there's Apple and Amazon as well as those I mentioned, and presumably Google is becoming YouTube Music), but this is how I listen to music now. I haven't bought a CD in years, and I've bought many thousands in my time.
It doesn't have to be super swish, just play the music. Getting it from elsewhere and using the WDM has always been unreliable.
Make it premium if you like. I'm considering moving to Roon, which is real money every month. Ask me for £50 extra per year and I wouldn't think twice about it; a tenner a month would probably make me hold out all of a half hour or so.
