I’m running roon. It’s expensive but self hosted, and has an excellent set of features around a library that seamlessly blends locally stored content with cloud content from either qobuz or tidal. It is great for discovery because I can click into the performers/composers of a track/album and see their other work. Or view a composition itself and see other artists who have performed it.

I wouldn’t say it’s for everyone but it’s been a good fit for me.
