Hi @pl_svn — The green highlighted track you are seeing is a reference, to how you’ve discovered the album you are currently seeing. Let me explain by using an example. If I click on the “playlist” button in Roon, a new page will pop up with various playlists, I choose one. Now, when that playlist opens I will have number of tracks listed and I have the option to select the “Artist” or “Album” of a song I like from that listing. If I hear a track that I REALLY like and want to see what else the album from which is came from has to offer, I will click on “Album” and Roon will bring me to the Album’s page. When you are viewing the album’s page the track you used to discover that album will be highlighted as a reference so you know where your “starting point” was. Hope this explanation helps and if you have anymore questions or issues, we are glad to help out. The same can also be done with “works”.
