Roon is expensive, but if you are a serious music fan, it’s 100% worth it.
I describe it to others as like talking to a super knowledgeable music store employee. It knows so much about each track, each musician, each band… cross-referencing them all, so you can go down a rabbit hole of hyperlinks learning about the music. It seamlessly mixes playlists across streaming and locally stored music. It does a decent job of streaming around the house to Apple, android, and audiophile devices. They just added an app that enables remote listening to your locally stored music.
