The first thing you need to know about Roon is that it can play all of your music with the best possible sound quality and transparency. When you install Roon, it goes through a process to learn your music library. Roon will play your music automatically and find tracks that it knows and that it thinks you will enjoy. If it doesn’t find it, it will ask you to add the files manually. Once you’re done, you can see the tracks that Roon thinks you will enjoy.
